A linear pair is a pair of adjacent angles formed when two lines intersect. The sum of the measures of a linear pair of angles is always 180 degrees.
1. Which of the following describes a linear pair of angles?
Two angles that add up to 90 degrees.
Two non-adjacent angles.
Adjacent angles that form a straight line.
Angles that are always congruent.
2. If one angle in a linear pair measures 70 degrees, what is the measure of the other angle?
20 degrees
90 degrees
110 degrees
180 degrees
3. The sum of the measures of angles in a linear pair is always degrees.
4. Linear pairs are always angles.
5. Angle A and Angle B form a linear pair. If the measure of Angle A is (3x + 10) degrees and the measure of Angle B is (2x - 5) degrees, find the value of x.
6. Explain why angles that form a linear pair are supplementary.
7. All adjacent angles form a linear pair.
True
False
8. The non-common sides of a linear pair always form a straight line.
True
False
