Ideas for Use Write the name of a lesson on the front of a blank card. Write a few study tips for that lesson on the back of the card. A polygon with three sides and three angles. Imagine your friend draws a shape with three sides and three angles. How would you classify the shape? It is a triangle. Use the blank cards to draw or write examples that will help you with concepts like the relationship between quadrilaterals and parallelograms. A quadrilateral with exactly one pair of parallel sides. Explain how a square and a trapezoid are different. Sample answer: A square has 2 pair of parallel sides. A trapezoid has 1 pair of parallel sides. The prefix peri- means all around. How does this help you remember the definition of perimeter? Sample answer: A perimeter is the distance around a shape. The shared endpoint where 2 rays meet in an angle. Vertex can mean the highest point of something. How is this similar to the math meaning? Sample answer: Both are about something coming to a point.
