Question

What are the measure of angle ADC and angle CBD for the parallelogram if angle DAB = 55° and angle ACB = 45° ? ​

Answer 1

Answer:

Angle ADC = 55℃

Angle CBD = 45°

Step by step explanation:

Given,

angle DAB=55°[ AB || CD ]

angle ACB=45°[ AC || BD ]

angle ADC = angle DB ( alternate interior angle )

so, angle ADC = 55°

and , angle ACB = angle CBD ( alternate interior angle )

so , angle CBD = 45°
