Sample questions

1. What is an angle?

   1. A figure with three sides
   2. A measure of rotation
   3. A straight line
   4. A point in space
   Show answer

   Answer: B. A measure of rotation

   An angle is formed when two rays meet at a common endpoint, and it represents a measure of rotation.

2. Which type of angle measures more than 90 degrees?

   1. Acute angle
   2. Right angle
   3. Obtuse angle
   4. Straight angle
   Show answer

   Answer: C. Obtuse angle

   An obtuse angle is defined as an angle that measures more than 90 degrees but less than 180 degrees.

3. If two angles are supplementary, what is the total measure of both angles?

   1. 90 degrees
   2. 180 degrees
   3. 360 degrees
   4. 270 degrees
   Show answer

   Answer: B. 180 degrees

   Supplementary angles are two angles that add up to 180 degrees.

4. If one angle measures 60 degrees, what is the measurement of its complement?

   1. 30 degrees
   2. 60 degrees
   3. 90 degrees
   4. 120 degrees
   Show answer

   Answer: A. 30 degrees

   The complement of an angle can be found by subtracting the angle from 90 degrees. Therefore, 90 - 60 = 30 degrees.

5. If a triangle has two angles measuring 45 degrees each, what is the measure of the third angle?

   1. 90 degrees
   2. 45 degrees
   3. 60 degrees
   4. 30 degrees
   Show answer

   Answer: A. 90 degrees

   In a triangle, the sum of interior angles is 180 degrees. If two angles measure 45 degrees each, the third angle is 180 - (45 + 45) = 90 degrees.
