Question

write all the properties of parallelogram ABCD​

Answer 1

Answer:

1)opposite sides are equal.

2)opposite angles are equal.

3)diagonals bisect one another

Answer 2

Answer:

A parallelogram is a two-dimensional geometrical shape, whose sides are parallel with each other. It is a polygon having four sides, where the pair of parallel sides are equal in length. Also, the interior opposite angles of a parallelogram are equal to each other. The area of parallelogram depends on the base and height of it.

Step-by-step explanation:

In the figure above, you can see, ABCD is a parallelogram, where AB || CD and AD || BC.

Also, AB = CD and AD = BC

And, ∠A = ∠C & ∠B = ∠D

Also, ∠A & ∠D are supplementary angles because these interior angles lie on the same side of the transversal. In the same way, ∠B & ∠C are supplementary angles.

Therefore,

∠A + ∠D = 180

∠B + ∠C = 180
