Ineed with these questions. three of them need to be checked and the last one i need answering.

(if you cannot see the attachments yet wait because that means i’m still attaching them)

Step-by-step explanation:

1. Correct. Corresponding vertices are (A, D), (B, E), and (C, F). The triangle names must list corresponding vertices in the same order. Thus the answer is the one you have chosen.

__

2. Look again. As in the first problem, corresponding vertices are in the same order. Line segment EF is named by the first two vertices in the triangle name, so the corresponding segment is LM, also named by the first two vertices of that triangle's name.

Segment FG is named by the last two vertices of the triangle's name, so the corresponding segment in the other triangle is also named by the last two vertices of the triangle's name: MN. Corresponding segments are proportional, so EF/LM = FG/MN.

3. Correct. Segment DB is congruent to itself. The halves of the bisected angle at D are congruent to each other, and the segments DA and DC are shown as congruent. Hence, SAS is an appropriate choice for showing congruence of the triangles.

4. The 1:1 ratio of these similar triangles tells you they are congruent, so ...

  AC = EC

  4x -3 = 2x +6 . . . . substitute the given expressions

  2x = 9 . . . . . . . . . . add 3-2x

  EC = 9+6 = 15 . . . substitute for 2x in the expression for EC

The question asks for AE, which is 2 times the length EC, so is ...

 AE = 2·EC = 2·15 = 30 . . . . feet

___

The only indication that the units are feet is that the answer choice with the number 30 has feet as its units. (We should be seeing "(4x-3) feet" as the measure of AC, for example.)

i had a similar work too, kindly contact professor james. so far he has handled 2 online tests and a paper for me. i attained 100% in both tests and 97% on the paper. kindly let him know that i referred you, i’m johnson.
