Answer: The answer is (B) If an angle has measure 90°, then it is a right angle. True.
Step-by-step explanation: The given conditional statement is
" If an angle is a right angle, then its measure is 90°."
We are to write the converse of the above conditional statement.
We know that if the statement is "If p, then q", then its converse will be "If q, then p".
So, the converse of our given statement will be
"If an angle has measure 90°, then it is a right angle."
Since this statement is always true, so the correct option is (B).
