3. Example 1 is known: as shown in Figure 1-1, in the quadrilateral ABCD, BC > Ba, ad = CD, BD bisects ∠ ABC,
verification: ∠ a + C = 180 °
analysis: because the horizontal angle is equal to 180 °， Therefore, we should consider transforming two angles which are not together into equal angles by congruence, and there is no congruent triangle in the graph. Therefore, the key to solve the problem is to construct isosceles triangle, which can be realized by "truncation and complement method". "
prove: intercept be = AB on BC, connect De, and then take the midpoint m of EC, Connecting DM
∵ AB = be
and ∵ BD bisecting ∠ ABC a d
∵ abd = ∠ EBD
in △ abd and △ EBD,
AB = be
∠ abd = ∠ EBD
BD = BD B e M C
{abd ≌ △ EBD (SAS) is shown in Figure 1-1
} ad = ed ∠ a = ∠ bed,
∵AD = DC ， ∴ED = DC ∴∠ C = ∠DEC
∴∠A + ∠C = ∠BED +∠DEC = 180 °< As shown in Figure 2-2, AE / / BC, ad and BD share & eth equally; EAB、Ð CBA, EC, point D
verification: ab = AE + BC
analysis 1: to prove that ab = AE + BC, observe that AD and BD are bisectors, so the Daed can be folded along a, so it is necessary to add an auxiliary line to intercept BF = BC on AB, and only need to dece AF = AE, then the problem can be solved, so how to dece AF = AE becomes the key to solve the problem. Because the sum of internal angles of Daed, DADB and DBD is 180 °， And & eth; EDC=180 °， Because AE / / be, therefore & eth; E+Ð C=180 ° Thus & eth; EAB+Ð CBA=180 °， Ad and BD are bisectors of angles, and we can dece & eth; 1+Ð 4=90 °， Thus, we can dece & eth; ADB=90 °， Thus & eth; 6+Ð 8=90 ° If we can dece & eth; 7=Ð 8, then we only need to dece Daed ≌ dafd, thus we can dece AE = AF, BC = BF, & eth; 1=Ð 2.

that is, ab = AE + BC
analysis 2: extend the extension line of BC intersecting ad to F. To prove AB = AE + BC, we only need to prove BF = AB and dece CF = AE. In order to prove CF = AE, we only need to dece two triangles Daed ≌ dfcd with CF and AE e to & eth; 5 = 6, AE / / BC, so & eth; 3=Ð F.

in Daed and dfcd, it is known that ad is the angular bisector of △ ABC, AB > AC, as shown in Fig. 3-1,
verification: AB-AC > bd-dc
analysis: in order to prove AB-AC > bd-dc, we need to transform the difference between AB and AC, the difference between BD and DC or their equal quantity into the edge of the same triangle, and then use the relationship between the three sides of the triangle to prove it

verification: ab = AC + CD.
analysis: from the conclusion analysis, "truncation" or "complement" can realize the transformation of the problem, that is, extending AC to e makes CE = CD, It is proved that: Method 1 (short complement method)

5. What do exchange currency and legal currency mean? Traditional digital currency platform trading only legal currency trading, that is, currency against data currency trading. If you want to buy other virtual currency, or improve the project investment, immediately online recharge currency to carry out the purchase; Or exchange the previous data into foreign currency, and then use the asset to purchase other virtual currencies. This kind of exchange method virtually improves the economic development and economic cost of investors
What do you mean by legal currency transaction and currency transaction
with the increase of the types of virtual currency and the graal expansion of the scope of application, the traditional legal currency transaction has been unable to consider the project investment requirements of investors, and a large number of investors have just begun to choose the currency transaction as the investment method. To put it bluntly, currency transaction is a kind of transaction that can complete the exchange between digital currencies. It can help customers not only improve the basic level of project investment, but also apply a more convenient and economical method to carry out virtual currency project investment
to some extent, currency trading can make full use of asset effect. In terms of brand image, if the decline of currency a and the rise of currency B can be predicted and analyzed in a certain period of time, investors can obtain the profits caused by the decline of currency a and the rise of currency B according to the A / b transaction to transaction, so as to enhance long-term investment. In addition, if the virtual currency sales market falls in the whole process, investors can also buy and sell according to usdt (virtual currency linked with us dollar), so as to rece losses and ensure property safety
on the other hand, e to the harm of control factors, some local government departments have completely prohibited financial enterprises from showing banking business for digital currency business process, or prohibited virtual currency to legal currency transactions in the region. In other words, virtual currency to legal currency transaction will not be carried out smoothly in some situations, and currency transaction can be used as an alternative method for customers to choose.
What do you mean by legal currency transaction and currency transaction
with the increase of the types of virtual currency and the graal expansion of the scope of application, the traditional legal currency transaction has been unable to consider the project investment requirements of investors, and a large number of investors have just begun to choose the currency transaction as the investment method. To put it bluntly, currency transaction is a kind of transaction that can complete the exchange between digital currencies. It can help customers not only improve the basic level of project investment, but also apply a more convenient and economical method to carry out virtual currency project investment

6. Eth trunk interface is a kind of interface that can be created dynamically. This type of interface can be bound with several physical Ethernet interfaces as a logical interface. The Ethernet interface added to the ETH trunk interface is called the member interface. Users only need to configure the ETH trunk interface, and these configurations will eventually be mapped to the member interface. The ETH trunk interface can be divided into routing mode and switching mode. The routing mode Ethernet trunk interface is similar to the routing mode Ethernet interface, which can configure IP address, run various routing protocols, MPLS VPN and other services; The ETH trunk interface of switching mode is similar to Ethernet interface of switching mode, which can join VLAN, run STP and other protocols
the application features of eth trunk interface include expanding interface bandwidth, increasing link reliability and load sharing of traffic

7. Linux can modify the network card name through the following steps:
1. Modify / etc / udev / rules.d/70-persistent-net.rules, change eth0 to EM1, and eth1 to em2. Note: you only need to modify the name, but not the kernel
2. To rename the network card configuration file, the ifcfg-eth0 file needs to be renamed to ifcfg-em1, and the ifcfg-eth1 file needs to be renamed to ifcfg-em2,
MV / etc / sysconfig / network scripts / ifcfg-eth0 / etc / sysconfig / network scripts / ifcfg-em1
MV / etc / sysconfig / network scripts / ifcfg-eth1 / etc / sysconfig / network scripts / ifcfg-em2
3 Edit the network card configuration file, modify the name, delete UUID (if not, do not use it), restart the server, after restart, the network card name has been modified, and the network is normal.

8. Let me tell you, EC expects that the consensus will be calculated by each node, so that all nodes in the whole network can reach a consensus in a very short time.
