Question

2. Two adjacent angles of a parallelogram are equal. What is the measure of each of
these angles?
​

Answer 1

HOPE THIS HELPS:

let the two angle= x

ATQ,

x+x = 180 (adjacent angles are supplementary)

2x = 180

x = 90

So, the 2 angles are 90 degree each

Answer 2

Answer:

Measure of the angles is 90°

Step-by-step explanation:

Let the name of the parallelogram be ABCD

Let the equal angles be angleA and angleB

angle=angleB

angleA+angleB= 180° (Co- interior)

=>angleA+angleA=180 (As angleA=angleB)

=>2(angleA)=180

=>angleA=180/2

=>angleA=90°

Therefore, angleB=90°

angleC=90° (opposite angles are equal)

angleD=90° (opposite angles are equal)

Therefore, the measure of each angles is 90°
