Sides of a Parallelogram

Sides of a Parallelogram

How to solve the sides of a parallelogram problems: property, example, and its solution.

Property

The parallel sides of a parallelogram are congruent.

The parallel sides of a parallelogram are congruent.
(= Same colored sides are congruent.)

Example

Find the values of x and y. Sides: y + 4, 2x + 1, 6, 9.

The blue sides are parallel sides in a parallelogram.

So the blue sides are congruent.

2x + 1 = 9

The red sides are parallel sides in a parallelogram.

So the red sides are congruent.

y + 4 = 6
