Question

What do I prove exactly in a Right Triangle Similarity?

Answer 1

i like your name

Answer 2

Thanks, can you help me? @needhelpplease112233

Answer 3

what grade are you in to be doin this stuff

Answer 4

11th.

Answer 5

It explains everything in detail except an example of a "given and prove"

Answer 6

sorry,but i dont know this

Answer 7

you mean that 2 triangles are similar?

Answer 8

I guess so.

Answer 9

This is my proof.
1. Draw ∆ABC Construction
2. Draw altitude CD with length h Construction
3. Let AC equal b, CB = a, AB equal c, AD = x, and DB= y Labeling
4. y + x = c Segment Addition Postulate
5. c/a = a/y & c/b = b/x Pieces of Right Triangles Similarity Theorem
6. b^2= cx a^2= cy Cross Product Property
7. a^2 + b^2 = cy + b^2 Addition Property of Equality
8. a^2 + b^2 = cy + cx Substitution
9. a^2 + b^2 = c ● y + x Distributive Property of Equality
10. a^2 + b^2 = c ● c Substitution
11. a^2 + b^2 = c^2 Multiplication

Answer 10

if it is this, then you generally have some proof identities, like : two sides with the same ratio and an isometric angle between them, 3 isometric angles and two isometric angles and 1 side with the same ration. You could use those

Answer 11

Thanks, but I don't know what an isometric angle is?

Answer 12

same angle

Answer 13

Which angles would I be proving are equal?
