What are two shapes that always have only two sets of parallel sides?
You're welcome.
Two shapes that always have only two sets of parallel sides are rectangles and parallelograms.
To understand why these shapes have two sets of parallel sides, let's break it down:
1. Rectangles: A rectangle is a quadrilateral with four right angles. Opposite sides of a rectangle are always parallel, which means there are two sets of parallel sides. To visualize this, draw a rectangle and notice that opposite sides are parallel and equal in length.
2. Parallelograms: A parallelogram is also a quadrilateral with two pairs of parallel sides. In a parallelogram, opposite sides are parallel and equal in length, just like in a rectangle. If you draw a parallelogram, you will see that there are two sets of parallel sides.
It's important to note that not all quadrilaterals have two sets of parallel sides. For example, a trapezoid has only one pair of parallel sides. So, when looking for shapes with only two sets of parallel sides, remember rectangles and parallelograms are the ones to consider.
