Final answer:
Angle 1 is congruent and complementary to Angle 2. The measure of Angle 1 is 45 degrees.
Step-by-step explanation:
In geometry, an angle is formed by two rays that share a common endpoint, called the vertex. Angles are measured in degrees (°) or radians (rad) and are used to describe the amount of rotation between the two rays.
Angle 1 is congruent and complementary to Angle 2. This means that Angle 1 and Angle 2 have the same measure and their measures add up to 90 degrees. Since the angles are congruent, the measure of Angle 1 is also 90/2 = 45 degrees.
