Question

ABCD is a parallelogram in which in which angle a is 110. Find the measure of each of the angles b,c,d

Answer 1

m < b = 70, m < c = 110 and m < d = 70 degrees.

Explanation:

The opposite angle a ( angle c) = a = 110 degrees (Property of a parallelogram).

The angle on the same line as a ( that is angle b) = 180 - 110 = 70 degrees.

(Property of a parallelogram).

Finally angle d which is opposite angle b = 70 degrees.
