Write the following compound statement symbolically.
The angle is right angle if and only if it is of measure 90°.
उत्तर
Let p: The angle is right angle.
q: The angle is of the measure 90°.
As the statements, p and q are connected by “if and only if” which is biconditional, so symbolically the statements can be expressed as p↔q.
