Front

What is the sum of the interior angles of a triangle?

Back

Front

What are the types of quadrilaterals?

Back

1. Square: all sides equal, all angles 90 degrees. 2. Rectangle: opposite sides equal, all angles 90 degrees. 3. Rhombus: all sides equal, opposite angles equal. 4. Trapezoid: at least one pair of parallel sides.
