Question

1. in parallelogram abcd, what is the measure of y°?

60
65
180
115

Explanation:

Step1: Use the property of parallelogram

In a parallelogram, opposite angles are equal and consecutive angles are supplementary. Also, \(\angle A\) and \(\angle C\) are not consecutive.

Step2: Apply the property

Since \(ABCD\) is a parallelogram, \(\angle A=\angle C\) (opposite angles of a parallelogram are equal). Given \(\angle A = 65^{\circ}\), so \(y=\angle C=\angle A\)

Answer:

\(65\) (corresponding to the second option \(65\))
