Question

This is a two part question just need help figuring out what exactly it is I need to mark up for the first section up on top and also on the second part of it I need help figuring out if both triangles are congruent and if they are need help stating the congruency

Answer 1

Given the triangles CDE and JLM

For the triangles we have the following:

1) CD = JL

2) CE = JM

3) DE = LM

So, there 3 pairs of congruent sides

So, the triangles are congrurent by S.S.S ( Side-Side-Side) postulate

C is corresponding to J

D is corresponding to L

E is corresponding to M

So,

$\triangle\text{CDE}\cong\triangle\text{JLM}$

For marking the triangles, see the following figure:
