Expert Solution & Answer

Answer to Problem 8CE

This person has over looked right angles, straight angles and reflex angles.

Explanation of Solution

Given information:

Planning to write an indirect proof that ∠A is an obtuse angle, B began by saying “Assume temporarily that ∠A is an acute angle”. What has B over looked.

Calculation:

A person wanted to write an indirect proof that ∠A is an obtuse angle.

He started off the proof by saying “Assume temporarily that ∠A is an acute angle”.

There is need to find out what person has over looked.

Start off an indirect proof by assuming temporarily that the given conclusion is incorrect.

In this case, the correct sentence would be:

“Assume temporarily that ∠A is not an obtuse angle”.

When ∠A is not an obtuse angle, it covers the entire set of angles that is not in the set of obtuse angles, which would be acute angles, right angles, straight angles and reflex angles.

By saying “Assume temporarily that ∠A is an acute angle”, this person has over looked right angles, straight angles and reflex angles.
