1. Which of the following statements best defines a linear pair of angles?
Two angles that add up to 90 degrees.
Two adjacent angles that form a straight line.
Two angles that share a common vertex.
Two non-adjacent angles that are equal.
2. If two angles form a linear pair, their sum is always:
90 degrees
180 degrees
360 degrees
Cannot be determined
3. A linear pair of angles are always angles.
4. If one angle in a linear pair measures 75 degrees, the other angle measures degrees.
5. Identify the linear pairs in the diagram below.
6. Angle A and Angle B form a linear pair. If Angle A is represented by (2x + 10)° and Angle B by (3x - 20)°, find the measure of both angles.
7. All adjacent angles are linear pairs.
True
False
8. If two angles are supplementary, they always form a linear pair.
True
False
9. Consider a straight line PQ. A ray OR originates from point O on PQ. If ∠POR = (5x - 15)° and ∠QOR = (2x + 5)°, find the value of x and the measure of each angle.
10. Draw two angles that form a linear pair and label their measures as (y + 30)° and (2y)°. Then, write an equation to solve for y and find the measure of each angle.
