  46. FORMING FORMULAS • LOOK FOR WAYS TO CUT UP THE PARALLELOGRAMS AND TRAPEZOIDS INTO TRIANGLES

  47. GOING INTO THE GALLERY • REMEMBER, THE HEIGHT IS ALSO THE ALTITUDE WHICH IS DRAWN PERPENDICULAR TO THE BASE

  48. A RIGHT-TRIANGLE PAINTING • DRAW A RIGHT TRIANGLE THAT HAS A 55 DEGREE ANGLE • EXTEND BOTH SIDES SO THAT THEY ARE AT LEAST 10 CM IN LENGTH

  49. A TRIGONOMETRIC SUMMARY • SIN A = OPPOSITE/HYPOTENUSE • COS A = ADJACENT/HYPOTENUSE • TAN A = OPPOSITE/ADJACENT

  50. A HOMEMADE TRIG TABLE • DRAW A RIGHT TRIANGLE USING THE ASSIGNED ANGLE FOR YOUR GROUP • MEASURE ALL THE SIDES • COMPUTE THE RATIOS OF SIN, COS, AND TAN
