Special Right Triangles 30°60°90° triangle The 30°60°90° refers to the angle measurements in degrees of this type of special right triangle In this type of right triangle, the sides corresponding to the angles 30°60°90° follow 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 can beThe first concept of a triangle is the pattern of x, x√3,2x which Sal represents as a ratio of 1, √3, 2 Using the Pythagorean Theorem, (1)^2 (√3)^2 = (2)^2 or 1 3 = 4 This ratio will be true of every triangle The second concept is to find the other sides if Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another The basic triangle ratio is Side opposite the 30° angle x Side opposite the 60° angle x * √ 3 Side opposite the 90° angle 2 x
Remembering the triangle rules is a matter of remembering the ratio of 1 √3 2, and knowing that the shortest side length is always opposite the shortest angle (30°) and the longest side length is always opposite the largest angle (90°)The property is that the lengths of the sides of a triangle are in the ratio 12√3 Thus if you know that the side opposite the 60 degree angle measures 5 inches then then this is √3 times as long as the side opposite the 30 degree so the side opposite the 30 degree angle is 5 /The triangle is called a special right triangle as the angles of this triangle are in a unique ratio of 123 Here, a right triangle means being any triangle that contains a 90° angle A triangle is a special right triangle that always has angles of measure 30°, 60°, and 90°
A triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle) Because the angles are always in that ratio, the sides are also always in the same ratioIf a triangle has angles of 30, 60 and 90 degrees it is called one of the SPECIAL TRIANGLES It is used extensively in mathematics because we can find EXACT answers for sine, cosine and tangent of the angles 30 and 60 degrees All the following triangles have angles of 30, 60 and 90 degrees! A is a scalene triangle and each side has a different measure Since it's a right triangle, the sides touching the right angle are called the legs of the triangle, it has a long leg and a short leg, and the hypotenuse is the side across from the right angle

Answer (1 of 3) If we take a triangle ABC, right angled at A And assume < B = 60°, < C = 30° Then, sin 60° = opposite side / hypotenuse => √3/2 = AC/BC = √3x / 2x & By pythagoras law, BC² = AB² AC² => BC² = x² 3x² = 4x² => BC = 2x Hence, ratio of the lengths of ABACBC = 1 √3 2Prove Side Ratios for Triangle = 1sqrt (3)2 A triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle) Because the angles are always in that ratio, the sides are also always in the same ratio
