Definition of a Parallelogram
Property
A parallelogram is a four-sided shape (quadrilateral) with two pairs of parallel sides. Opposite sides are equal in length, and opposite angles are equal in measure.
Examples
- A square is a special parallelogram with four equal sides and four 90° angles.
- A rhombus with a side length of 5 is a parallelogram where all four sides are equal, but the angles may not be 90°.
- A standard rectangle is also a parallelogram because its opposite sides are parallel.
Explanation
Think of a rectangle that's been pushed over! Its opposite sides stay parallel and equal, but the angles aren't necessarily perfect right angles anymore. It's a shape that loves to lean while keeping its opposite sides perfectly aligned, just like a disciplined dancer mid-pose.
