Answer 1

Yes if an angle measures 90 degrees then this angle is called right angle.

Answer 2

Conditional: If an angle is a right angle, then its measure is 90°. Converse: If the measure of an angleis 90°, then it is a right angle. Since the conditional and its converse are true, the biconditional is true. For a biconditional statement to be true, both the conditional statement and its converse must be true.
