Question

In a rhombus ABCD,AC=AD. Find the measure of angle B and angle DCB

Answer 1

Answer:

angle B= 60

DCB=120

Step-by-step explanation:

given AC=AD

but we know that AD = CD as well so now triangle

ACD will be equilateral triangle

so angle D=60

so angle B =60

since opposite angles in a rhombus are equal

and adjacent angles add up-to 180

so DCB +60=180

DCB=180-60=120
