Answer:
They are both quadrilaterals and they both have equal and parallel opposite sides.
Explanation:
Rectangles and parallelograms both have four sides, and thus are quadrilaterals.
Quadrilaterals
The definition of a quadrilateral is a 2-D shape with 4 sides and 4 angles. Rectangles and parallelograms both fall under this category. So, they both have all the attributes listed in the definition.
This means 3 shared attributes of rectangles and parallelograms are:
- 2 dimensional
- 4 sides
- 4 angles
Opposite Sides
Rectangles and parallelograms also have unique relationships between opposite sides. Remember that opposite sides are directly across from each other and not adjacent. In both shapes, opposite sides are parallel. This means that if the sides were to continue forever, they would never intersect. Also, opposite sides are equal. By this, I mean that the lengths of opposite sides are equal. Another way to say this is that opposite sides are congruent.
