Which statements are true? Select all that apply.

Question

Select 5 correct answer(s)
Question 6 options:

Same side interior angles are supplementary.

Alternate interior angles are congruent to each other.

An angle that is exactly 90 degrees is called acute.

If an angle is 180 degrees then it is called a straight angle.

The common endpoint of two rays that form an angle is called a vertex.

Supplementary angles are two angles that add up to 180 degrees.

Answer 1

The following statements are true:

1. Same side interior angles are supplementary. (True)
2. Alternate interior angles are congruent to each other. (True)
3. If an angle is 180 degrees then it is called a straight angle. (True)
4. The common endpoint of two rays that form an angle is called a vertex. (True)
5. Supplementary angles are two angles that add up to 180 degrees. (True)

The false statement is:

• An angle that is exactly 90 degrees is called acute. (False - An angle that is exactly 90 degrees is called a right angle.)

So, the five correct answers are the first four statements and the last one about supplementary angles.
