Question

1. what is the negation of the following statement?

m∠a is greater than 90.

m∠a is not less than 90.

m∠a is less than or equal to 90.

Explanation:

Step1: Analyze the original statement

The original statement is \(m\angle A>90\).

Step2: Find the negation

The negation of \(a > b\) is \(a\leq b\). So the negation of \(m\angle A>90\) is \(m\angle A\leq90\), which means \(m\angle A\) is less than or equal to 90.

Answer:

\(m\angle A\) is less than or equal to 90.
