Answer 1

Determine whether the conditional and its converse are both true. If both are true, combine them as a biconditional. If either is false, provide a counterexample.

If an angle is a right angle, its measure is 90.
If an angle measure is 90, the angle is a right angle.

One statement is false. If an angle measure is 90, the angle may be an obtuse angle.
One statement is false. If an angle is a right angle, its measure may be 180.
Both statements are true. An angle is a right angle if and only if its measure is 90.
Both statements are true. The measure of an angle is 90 if and only if it is not a right angle.

Answer 2

I think its Both statements are true. An angle is a right angle if and only if its measure is 90.
