Aboutabout this video. transcript. a 30 60 90 triangle is a special right triangle with angles of 30, 60, and 90 degrees. it has properties similar to the 45 45 90 triangle. the side opposite the 30 degree angle is half the length of the hypotenuse, and the side opposite the 60 degree angle is the length of the short leg times the square root.

This video tutorial provides a basic introduction into 30 60 90 triangles. it explains how to find the value of the missing side of other triangles using th. More lessons for grade 7 and grade 8 math worksheets. 30 60 90 triangles. a 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 1:2. The lengths of the sides of a 30° 60° 90° triangle are in the ratio of 1 : √3 : 2. you can also recognize a 30° 60° 90° triangle by the angles. as long as you know that one of the angles in the right angle triangle is either 30° or 60° then it must be a 30° 60° 90° special right triangle. a right triangle with a 30° angle or 60.

The lengths of the sides of a 30° 60° 90° triangle are in the ratio of 1 : √3 : 2. you can also recognize a 30° 60° 90° triangle by the angles. as long as you know that one of the angles in the right angle triangle is either 30° or 60° then it must be a 30° 60° 90° special right triangle. a right triangle with a 30° angle or 60. The ratio of the side lengths of a 30 60 90 triangle is 1 ∶ √3 ∶ 2. this means that if the shortest side, i.e., the side adjacent to the 60° angle, is of length 𝑎, then the length of the side adjacent to the 30° angle is 𝑎√3, and the length of the hypotenuse is 2𝑎. in this case we have 𝑎√3 = 15 ⇒ 𝑎 = 5√3. The measures of its angles are 30 degrees, 60 degrees, and 90 degrees. and what we're going to prove in this video, and this tends to be a very useful result, at least for a lot of what you see in a geometry class and then later on in trigonometry class, is the ratios between the sides of a 30 60 90 triangle.
