Worked examples

A few of the question types, with full solutions, so you know what to expect.

Angle sum. The interior angles of a quadrilateral add up to...

  1. 360°
  2. 180°
  3. 540°
  4. 90°

Answer: 360°

Angle sum. A quadrilateral has angles 100°, 85°, 95° and x. Find x.

  1. 80°
  2. 90°
  3. 75°
  4. 100°

Answer: 80°

x = 360° − (100° + 85° + 95°)

= 360° − 280°

Angle sum. A quadrilateral has angles 110°, 140° and two equal angles x. Find x.

  1. 55°
  2. 60°
  3. 50°
  4. 65°

Answer: 55°

2x + 110° + 140° = 360°

2x = 110°

Parallelogram. In parallelogram ABCD, angle A = 110°. What is angle C?

  1. 110°
  2. 70°
  3. 90°
  4. 55°

Answer: 110°

Opposite angles of a parallelogram are equal.

Parallelogram. In parallelogram ABCD, angle A = 110°. What is angle B?

  1. 70°
  2. 110°
  3. 90°
  4. 80°

Answer: 70°

A and B are co-interior: they add to 180°.

180° − 110°
