6-86.

Write a converse for each conditional statement below. Then, assuming the original statement is true, decide if the converse must be true or not.

1. If the base angles of a triangle are congruent, then it is isosceles.

To write a converse, switch the hypothesis and conclusion of the conditional statement.

Converse: If a triangle is isoceles, then its base angles are congruent. Always true.

2. If a figure is a triangle, then the sum of the angles in the figure is $180º$.

If the sum of the angles in a figure is $180º$, is the figure always a triangle?

3. If I clean my room, then my mom will be happy.

Is your mom always happy solely because you cleaned your room?
