Answer:

Opposites sides of a parallelogram are equal and parallel to each other.

Opposite angles are equal. ∠A= ∠C, and ∠B = ∠D

All the angles of a parallelogram add up to 360o. ∠A + ∠B + ∠C + ∠D = 360o.

The consecutive angles of a parallelogram are supplementary

Answer 2

Answer:

1) 8

2) 135

3) False

4) 45

5) Rhombus

Step-by-step explanation:

1) AD=BC

x+10= 18

x=18-10=8

2) <D+<C=180

45+<C=180. ------<D=45

<C=180-45=135

3) Diagonal of parallelogram is bisector but not perpendicular.

4) <D=<B (opposite angles are equal)

<B = 45

hope you understand the step
