Question

Can someone please help me. I don't understand this at all.

use congruency and similarity postulates and theorems to prove whether these two are or not.?

If someone can figure this out, can you Please include all of the necessary work to prove or disprove congruency/similarity.

Answer 1

Their Congruent, because the degrees are all the same but the left is just 2 times bigger.

Answer 2

Congruent means having the same size and shape. They have the same shape but not the same size so they are NOT congruent. They are similar though because there is a theorem that say "If two angles of one triangle are congruent to two angles of a second triangle, then the two triangles are similar.

Answer 3

Oh sorry... Totally mixed up the definition... but yeah their similar not congruent.

Answer 4

So the two triangles i showed you are similar but not congruent? Just trying to confirm this?

Answer 5

Yes.

Answer 6

So how would show the work to prove or disprove similarity or congruency? I know what AAS & SAS are but i don't know how use any of those to show the work

Answer 7

What similarity theorems do you have?

Answer 8

All i know is the only one that could not be used for this one is SAS

Answer 9

So the reason you are having trouble is because you do not know what theorems you have had. No one on OS can help you with that because we don't know either.

Answer 10

ok i understand. One thing i know for sure is that the pictures that i posted on here are similar but no congruent, so i have that down. All i have to do know is figure out how to show proof that it's similarity but not congruency.

Answer 11

You only know that the angles are congruent. You cannot show congruence without knowing at least 1 side is congruent.

Answer 12

ok & thanks for the help
