Consider an equilateral triangle of side 2 units. Looking at the 30-60-90 triangle made by the angle bisector, fill in the following values below. 60⁰ 30% 1 1 Enter the answer in terms of fractions. To type your equations, you can enter square root symbols, Greek letters and subscripts by selecting the MathType popup button (red radical) in the answer box. To enter subscripts, press the first right-facing arrow in menu of the popup. For Greek letters, press the right-facing arrow next to the alpha (a) symbol. Using the Pythagoroen Theorem, the third side of the 30-60-90 triangle is sin 60° cos30° = sin 30° cos60° = tan30° = cot60° = Memorizing these trigonometric values will help build a good mathematical foundation.
