One of the two special right triangles you'll be facing in trigonometry is the triangle The other one is the 45 45 90 triangle These triangles are special triangles because the ratio of their sides are known to us so we can make use of this information to help us in right triangle trigonometry problems(π / 6), 60°This is a triangle whose three angles are in the ratio 1 2 3 and respectively measure 30°
A triangle is a special right triangle with some very special characteristics If you have a degree triangle, you can find a missing side length without using theA 30 60 90 triangle is a special type of right triangle What is special about 30 60 90 triangles is that the sides of the 30 60 90 triangle always have the same ratio Therefore, if we are given one side we are able to easily find the other sides using the ratio of 12square root of three This special type of right triangle is similar to the 45 45 90 triangleFollow a ratio of 1√ 32 Thus, in this type of triangle, if the length of one side and the side's corresponding angle is known, the length of the other sides

(Theorems 3 and 9) Draw the straight line AD bisecting the angle at A into two 30°We know that in a 3060=90 triangle, the smallest side corresponds to the side opposite the 30 degree angle Additionally, we know that the hypotenuse is 2 times the value of the smallest side, so in this case, that is 10 The formula for , so orSince the right angle is always the largest angle, the hypotenuse is always the longest side using property 2 We can use the Pythagorean theorem to show that the ratio of sides work with the basic triangle above a 2 b 2
