In the rhombus, angle 1 = 140. What are angles 2 and 3? The diagram is not to scale.

Solution:

In a rhombus,

Angles which are opposite to each other are equal

As angle 1 is 140° so angle 2 is also 140°.

Similarly we know that

Consecutive angles are equal to 180°

It refers to that the angle between 1 and 2 is 40°

As angle 3 is half of that

Angle 3 = 20°

Therefore, the angles 2 and 3 are 140° and 20° respectively.

In the rhombus, angle 1 = 140. What are angles 2 and 3? The diagram is not to scale.

Summary:

In the rhombus, angle 1 = 140°. The angles 2 and 3 are 140° and 20° respectively. In a rhombus, angles which are opposite to each other are equal.
