Question

Q) ABCD is a parallelogram a.Name the pairs of parallel sides. b.If ∠A=60°, find ∠D

Answer 1

Answer:

parallel sides are AD = BC and;

AB = DC.

And; if <A = 60°

Then, < D= 120°.

Step-by-step explanation:

- we all know that opposite sides of parallelogram are parallel ( because it's a property of parallelogram).

-So, that's why

AD = BC, AB = DC.

And; we know that too that sum of corresponding angle are 180°

So, 60°+ x = 180°

x = 180°-60°

x = 120°.

Answer 2

Answer:

seg AB || seg CD

angle A =60° then angle D = 60°

Step-by-step explanation:

bcoz angle A and D are opposite angles and oppasite angles of a parallelogram are congruent
