Converses help: are converses of statements true or false?

[Rinnie]

If the quadrilateral is an isosceles trapezoid, then a pair of base angles are congruent.

If the quadrilateral is a kite, then the nonvertex angles are congruent.

If the quadrilateral is a kite, then the major diagonal bisects the vertex angles.

I'm really confused about the converses. I got false for all of them?

Hello, Rinnie!

I answered this question at another math site.

In the last one, the converse is true.
