Answer 2

m trying to add a picture but I cant?

Answer 3

@DSS

Answer 4

k

Answer 5

Can you draw the picture?

Answer 6

okay se if that worked

Answer 7

It did...give me a min

Answer 8

Its not a test I swear. Its homework and I dont understand at all. I have a REALLY low graded in geometry and need to make a good grade on this

Answer 9

i hated proofs somehow i made it through honors geometry with an A

Answer 10

@sweetburger Yeah Im in honors geometry and I havea 72. I used to be a straight A student until FLVS.

Answer 11

I hate proofs...i'm terrible at them. I'll continue to try to figure it out.

Answer 12

@DSS okay thanks so much! Lol I suck at them too.

Answer 13

DE and AC are parallel and AB is a transversal. Therefore, angle D = angle A (corresponding angles).
Similarly, angle E = angle C.
Triangles BDE and BAC are similar.

Answer 14

@ranga sorry Im kinda confused. I suck at this

Answer 15

There are two parallel lines shown. A transversal cuts them. The two angles marked (1) are equal because they are corresponding angles.

Answer 16

Okay I understand that. That makes more sense.

Answer 17

DE and AC are two parallel lines in the problem. BA is a transversal that cuts them. Therefore, angle BDE = angle BAC because they are corresponding angles.

Answer 18

In the triangles BDE and BAC, we just proved that angle BDE = angle BAC because they are corresponding angles. The angle B is shared by both triangles. We say angle B = angle B because of reflexive property of equality. If two angles of one triangle is equal to two angles of another triangle, then the two triangles are similar.

Answer 19

So its C right?

Answer 20

Yes.

Answer 21

Okay THANK YOU SO MUCH YOU"RE A LIFE SAVER. Can you help me with one more?

Answer 22

I can try.

Answer 23

It is the same problem posted again.

Answer 24

I even learned something.

Answer 25

They are trying to prove Pythagorean Theorem and so the Pythagorean Theorem itself cannot be used for justification. All the other three answer choices have been used properly in the proof.

Answer 26

so are you saying its b?

Answer 27

Yes. In the proof they have used:
Addition Property of Equality in the statement y + x = c
Pieces of Right Triangles Similarity Theorem in the statement: c/a = a/ y and c/b = b/x
Cross Product Property in the statement: a^2 = cy and b^2 = cx

But they have not used Pythagorean Theorem obviously because the whole proof is to prove the Pythagorean Theorem and therefore they cannot use it in the proof.

Answer 28

okay thanks!

Answer 29

you are welcome.
