In the rhombus m∠1=160°m∠1=160° . What are m∠2m∠2 and m∠3m∠3 ? The diagram is not drawn to scale.

In a rhombus, opposite angles are equal. Since angle 1 is 160°, angle 3 (opposite angle 1) is also 160°. Therefore, m∠3 = 160°.

The sum of the angles in any quadrilateral is 360°. Since opposite angles in a rhombus are equal, we can determine that angle 2 (opposite angle 4) is also 160°. Therefore, m∠2 = 160°.
