Sketch an equilateral triangle. Draw a perpendicular bisector from your top vertex to the bottom side, making two right triangles. Fill in the all of the angle measures using your knowledge of equilateral triangles and bisectors. If one side is 10 inches, fill in as many sides and pieces of sides as possible.
