Write converse, inverse and contrapositive of the following conditional statement :
''If an angle is a right angle, then its measure is `90^(@)`''.

Answer

Converse : If measure of an angles is `90^(@)`, then it is a right angles. Inverse : If an angle is not a right angles, then its measure is not `90^@)`.
Contrapositive : If measure of an angle is not `90^(@)`, then it is not a right angle.
