In Geometry I learned about the properties of parallelograms and used the properties to design a piece of stained glass. The inspiration for my stained glass was a deck of cards. The shapes I included in my design were triangles, squares, rectangles, circles, and parallelograms. I made sure that my parallelograms abided by the properties of parallelograms which are opposites are congruent, opposite are parallel, opposite angles are congruent, consecutive angles are supplementary, and diagonals bisect each other.
