Question

1. if quadrilateral abcd is parallelogram and m∠a is 78.2°, what is the measure of ∠c?

Explanation:

Step1: Recall the property of parallelogram

In a parallelogram, opposite angles are equal.

Step2: Apply the property

Since \(ABCD\) is a parallelogram and \(\angle A\) and \(\angle C\) are opposite angles, \(m\angle C=m\angle A\)

Answer:

\(78.2^{\circ}\)
