Explain Pythagorean Theorem Proof Practice Test

Theorem: If $a^2+b^2=c^2$, then the triangle is right. Converse: If the triangle is right, then $a^2+b^2=c^2$.

Theorem: If a triangle is right, then $a^2+b^2=c^2$. Converse: If $a^2+b^2=c^2$ (with $c$ the longest side), then the triangle is right.

Theorem and converse are the same statement, so there is no difference.

Theorem: If $a+b=c$, then the triangle is right. Converse: If the triangle is right, then $a+b=c$.
