Special Angles: 30 and 60. Let us first consider 30˚ and 60˚. These two angles form a 30˚-60˚-90˚ right triangle as shown. The ratio of the sides of the triangle is 1:√3:2 . From the triangle we get the ratios as follows: Special Angles: 45 and 90 Next, we consider the 45˚ angle that forms a 45˚-45˚-90˚ right triangle as shown. So let's look at a very simple 45-45-90: The hypotenuse of this triangle, shown above as 2, is found by applying the Pythagorean Theorem to the right triangle with sides having length 2 . The base angle, at the lower left, is indicated by the "theta" symbol ( θ, THAY-tuh), and is equal to 45°. Trig ratios of special triangles. Learn to find the sine, cosine, and tangent of 45-45-90 triangles and also 30-60-90 triangles. Trigonometric ratios of special angles. This lesson will summarize the trigonometric ratios of special angles taken from lesson #1 to lesson #6.We show you these results here before we move on to more complicated topics. Chart with the sine, cosine, tangent value for each degree in the first quadrant

The trig functions for 30∘,45∘,60∘ are based on two simple geometric figures: the square and the equilateral triangle. The square has four sides of equal length ,
