Sample Questions

1multiple choice

A square has diagonals of length 16 cm each. What is the length of each segment when the diagonals bisect each other?

Show answer

8 cm

Each diagonal is 16 cm. Since the diagonals bisect each other, each diagonal is divided into two equal parts. So each segment is 8 cm.

In a square, one diagonal bisects an angle of 90°. What is each half-angle?

Show answer

45°

A diagonal of a square bisects the angle of the square. So 90° is divided into two equal parts: 90 ÷ 2 = 45°.

A rhombus has one angle equal to 50°. What are the two opposite angles of the rhombus?

Show answer

50° and 50°

In a rhombus, opposite angles are equal. If one angle is 50°, the opposite angle is also 50°.

4multiple choice

A rhombus has one angle 50° and a diagonal splits the adjacent angle into two equal parts. What is each of those equal parts if the triangle around the diagonal gives a total of 180°?

Show answer

65°

The two equal parts are marked as a and a. Using the triangle angle sum, a + a + 50 = 180. So 2a = 130 and a = 65°.
