Question

I having trouble understanding these questions over pythagorean theorem. I can send photos so it's understandable.

Answer 1

We will be creating two triangles: Triangle ABC and Triangle CDE

From the two figures drawn above, Triangle ABC is similar to Triangle CDE

Line AB = Line DE

Line BC = Line DC

Line AC = Line CE

< D is equal to 90 degrees and this is similar to angle B

Hence, < D = < B

Also, triangle similarity proportion can be establish

`(AB)/(DE)\text{ = }(BC)/(DC)\text{ = }(AC)/(CE)`
