Question

Determine whether the angle to the right is acute, right, obtuse, or straight. If it is a right or straight angle, indicate the number of degrees in the angle.

1) Acute
2) Right
3) Obtuse
4) Straight

Answer 1

To determine the type of angle, measure it with a protractor and compare it to reference angles.

Step-by-step explanation:

To determine whether an angle is acute, right, obtuse, or straight, we need to measure the angle using a protractor and compare it to the reference angles.

An acute angle is less than 90 degrees, a right angle is exactly 90 degrees, an obtuse angle is greater than 90 degrees but less than 180 degrees, and a straight angle is exactly 180 degrees.

For example, if we measure the angle to be 45 degrees, it is acute. If we measure the angle to be 90 degrees, it is a right angle. If we measure the angle to be 120 degrees, it is obtuse. If we measure the angle to be 180 degrees, it is a straight angle.
