  1. Math 2Y 30°-60°-90° Triangles

  2. 30-60-90 Δ Theorem HYPOTENUSE = 2x LONGER LEG = x SHORTER LEG = x 60o 2x x 30o

  3. Example #1: Solve for d & e Remember to label your drawing with x, x√3 and 2x!! e = 2x d = x __ __ 30o 18 = x√3

  4. Example #2: Solve for a & c Remember to label your drawing with x, x√3 and 2x!! c = 2x 10 = x __ __ 30o a = x√3

  5. Assignment Use your textbook… pg. 155 #1,3,5,7,9 pg. 156 #19-24 (Be sure to copy the picture and label your sides!)
