Worked practice questions

Two straight lines cross. One angle formed is 50 degrees. The angle opposite to it is what?

  1. 50 degrees
  2. 40 degrees
  3. 130 degrees
  4. 100 degrees
Show answer and solution

Correct answer: A. 50 degrees

1. Opposite angles formed by two crossing lines are vertical angles. 2. Vertical angles are always equal. 3. So the opposite angle is also 50 degrees. The neighbouring angles are 130 degrees. _Source: Wikipedia, Angle (CC BY-SA 4.0), Adjacent and vertical angles_

Two angles of a triangle are 50 degrees and 60 degrees. What is the third?

  1. 110 degrees
  2. 70 degrees
  3. 80 degrees
  4. 130 degrees
Show answer and solution

Correct answer: B. 70 degrees

1. The three angles of a triangle add up to 180 degrees. 2. 50 + 60 = 110 degrees. 3. Third angle = 180 - 110 = 70 degrees. 4. The value 130 comes from subtracting only 50, and 110 is the sum of the two given angles. _Source: Wikipedia, Triangle (CC BY-SA 4.0), Triangle_

Each angle of an equilateral triangle measures how many degrees?

  1. 45
  2. 60
  3. 30
  4. 90
Show answer and solution

Correct answer: B. 60

1. All three angles of an equilateral triangle are equal. 2. They add up to 180 degrees. 3. Each angle = 180 / 3 = 60 degrees. _Source: Wikipedia, Equilateral triangle (CC BY-SA 4.0), Equilateral triangle_
