This roof exhibits a trapezoid because it has two congruent bases and non congruent legs. Rooves are used as a covering for a building or house. They are used by almost everyone. I found this object directly behind Severn School.
This is a picture of the side of a dumbbell, it shows a regular hexagon because it has 6 congruent sides. This object was found on the weight rack on my basement and is almost exclusively used for physical fitness.
