Sample questions

1. What is an angle?

   1. A figure with three sides
   2. A measure of rotation
   3. A line segment
   4. A type of triangle
   Show answer

   Answer: B. A measure of rotation

   An angle is defined as a measure of rotation between two rays that share a common endpoint. The correct answer is 'A measure of rotation'.

2. If one angle in a triangle is 50 degrees and another is 60 degrees, what is the third angle?

   1. 70 degrees
   2. 80 degrees
   3. 90 degrees
   4. 100 degrees
   Show answer

   Answer: A. 70 degrees

   In a triangle, the sum of angles is always 180 degrees. Therefore, the third angle is 180 - 50 - 60 = 70 degrees.

3. If two angles are supplementary, what is their total measure?

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

   Answer: B. 180 degrees

   Supplementary angles are those that add up to 180 degrees.

4. If the measure of an angle is tripled and equals 180 degrees, what is the original measure of the angle?

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

   Answer: B. 60 degrees

   Let the original angle be x. Then 3x = 180 implies x = 60 degrees.

5. If a polygon has 8 sides, what is the sum of its interior angles?

   1. 720 degrees
   2. 900 degrees
   3. 1080 degrees
   4. 1800 degrees
   Show answer

   Answer: C. 1080 degrees

   The sum of interior angles of a polygon can be found using the formula (n-2) * 180, where n is the number of sides. Therefore, for an 8-sided polygon, the sum is (8-2) * 180 = 1080 degrees.
