What a rip-off
                 1. DRAW A TRIANGLE (try to
                    use up a large portion of the
                    grid paper)

                 2. LABEL THE THREE
                    ANGLES (example a,      b, c)

                 3. NAME YOUR TRIANGLE
                    (example abc)

                 4. MEASURE EACH OF THE
                    THREE ANGLES AND WRITE
                    THE MEASURE ON EACH
                    ANGLE (example a = 37º)

                 5. CUT OUT YOUR TRIANGLE

                 6. RIP OFF THE THREE ANGLES
                   OF YOUR TRIANGLE

                 7. GLUE YOUR ANGLES ON TO
                   THE “ANGLES CAN BE A REAL
                   RIP OFF” PAGE.

                 1. DRAW A QUADRILTERAL
                    (try to use up a large portion
                    of the grid paper)

                 2. LABEL THE FOUR
                    ANGLES
                    (example a, b, c, d)

                 3. NAME YOUR
                    QUADRILATERAL
                    (example abcd)

                 4. MEASURE EACH OF THE
                    FOUR ANGLES AND WRITE
                    THE MEASURE ON EACH
                    ANGLE (example a = 37º)

                 5. CUT OUT YOUR
                    QUADRILATERAL

                 6. RIP OFF THE FOUR ANGLES
                   OF YOUR TRIANGLE

                 7. GLUE YOUR ANGLES ON TO
                   THE “ANGLES CAN BE A REAL
                   RIP OFF” PAGE.
