Question

11. Higher Order Thinking Using what you know

about angle pairs formed by parallel lines and a
transversal, how are 21, 22, 23, and 24 related
in the trapezoid? Explain.

Answer 1

m∠1 + m∠3 = m∠2 + m∠4

Explanation:

In the figure attached,

In the given trapezoid if two sides AB and CD are parallel and AD is a transverse,

m∠1 + m∠3 = 180°

Similarly, if AB and CD are parallel and BC is a transverse,

m∠2 + m∠4 = 180°

Therefore, m∠1 + m∠3 = m∠2 + m∠4 is the relation between these angles.
