Sample Additional Practice Exercise 1

Draw a box around the objects that look like a triangle. Mark an X on the objects that look like a circle.

A round clock, a square picture frame, a triangular pendant, and a quarter. The clock and quarter have Xs. The pendant has a box around it.

A circle is round. It has no straight sides and no vertices. So, the clock and the quarter are circles. A triangle has 3 sides and 3 vertices. So, the pendant is a triangle.
