Question

if an angle is greater than 90° then it obtuse. what is the contrapositive to this? if an angle is not greater than 90, then it is not obtuse if an angle is not obtuse then it is not greater than 90. if an angle is 90, then it is right if an angle is not greater than 90 then it must be acute

Explanation:

The contrapositive of a conditional statement "if p then q" is "if not q then not p". Here, p is "an angle is greater than 90°" and q is "it is obtuse". So the contrapositive is "if an angle is not obtuse then it is not greater than 90°".

Answer:

If an angle is not obtuse then it is not greater than 90.
