Question

BE is the bisector of ABC and CD is the bisector of ACB . Also, XBA . Which of AAS, SSS, SAS, or ASA would you use to help you prove BL ≅ CM?

Answer 1

This drawing has to be marked up so that we can see what is going on.

Answer 2

Look at this.

Answer 3

K

Answer 4

Done

Answer 5

Now, look at this.

Answer 6

done

Answer 7

In the next drawing, we will pull apart triangles BML and BCL.

Answer 8

k

Answer 9

It's time to choose the answer. Look at the two triangles at the top. By what postulate are they congruent?

Answer 10

We have used that postulate already in another problem when I explained about the included side.

Answer 11

Are you looking at the two green triangles?

Answer 12

yes

Answer 13

Do you see two pairs of congruent angles marked?

Answer 14

thinking dont tell me and yes

Answer 15

wait...

Answer 16

im trying to remember the rules

Answer 17

Here's a good resource to study:

http://www.mathwarehouse.com/geometry/congruent_triangles/

Answer 18

Look over there and you will see the scenario we have here and the name of the congruence postulate.

Answer 19

ok

Answer 20

So, which option?

Answer 21

asa

Answer 22

im going to practice this

Answer 23

Yes, that is NOT the same as AAS. AAS is the angles and the non-included side.

So, study up on the ways to prove triangles congruent. The diagrams at that link make it easier to remember.

Answer 24

i was going to aas good thing i didnt lol but thanks so much for all your help!

Answer 25

Glad to help. Again, study those ways to prove these triangles congruent and how the diagrams look. It is morning here but whatever time of day it is where you are, have a great day or a good night.

Answer 26

its 6:52am but have a great day! cya later

Answer 27

We're in the same time zone. Wow. I'll catch you on Open Study later.

Answer 28

ok ::)
