Geometry: Angles

An angle measures 35 degrees. Classify the angle as acute, right, obtuse, straight, or reflex. Explain your choice.

An angle measures 118 degrees. Classify the angle as acute, right, obtuse, straight, or reflex. Explain your choice.

Use a protractor to measure angle ABC. Ray BA points straight left from point B, and ray BC points up and to the right. Record the angle measure to the nearest 5 degrees.

Two angles are complementary. One angle measures 27 degrees. What is the measure of the other angle?

Two angles are supplementary. One angle measures 64 degrees. What is the measure of the other angle?

Angles x and 72 degrees form a straight line. Write and solve an equation to find x.

Two vertical angles are formed by intersecting lines. One angle measures 83 degrees. What is the measure of the vertical angle across from it?

Two intersecting lines create four angles. One angle measures 122 degrees. Find the measures of the other three angles.

In a triangle, two angles measure 45 degrees and 65 degrees. What is the measure of the third angle?

In a triangle, the angle measures are x degrees, 2x degrees, and 3x degrees. Find the value of x and the measure of each angle.

Lines m and n are parallel. A transversal crosses them. An angle on line m measures 110 degrees. The corresponding angle on line n is labeled y. What is y?

Lines p and q are parallel. A transversal crosses them. An interior angle on one side of the transversal measures 74 degrees. The alternate interior angle is labeled z. What is z?

A full turn is 360 degrees. A student turns 90 degrees to the right, then 45 degrees more to the right. How many degrees has the student turned in all, and what type of angle is the total turn?

An angle is 25 degrees more than a right angle. What is the angle measure, and how should it be classified?

Four angles meet at a point. Three of the angles measure 80 degrees, 95 degrees, and 110 degrees. What is the measure of the fourth angle?
