Question

how would you prove that the diagonals of a rhombus are perpendicular?

Answer 1

Given: Rhombus ABCD
Prove: AC is perpendicular to BD

I'm not doing the proof, but here's the strategey you need.
First use SSS to prove triangles ABC and ADC congruent.
BY CPCTC, angles BAE and DAE are congruent.
Use SAS to prove triangles BAE and DAE congrunt.
By CPCTC, angles AEB and AED are congruent.
When lines intersect forming adjacent congruent angles, the lines are perpendicular.
