A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees. The side opposite the 60° angle will be the middle length, because 60 degrees is the mid-sized degree angle in this triangle.
What are the formulas for a 30-60-90 Triangle?
30-60-90 Triangle Rule
| Base is given | Perpendicular is given |
|---|---|
| The perpendicular of the triangle ABC is AB = (a /√3) The hypotenuse of the triangle ABC is AC = (2a)/√3 | The base of the triangle DEF is EF = √3a. The hypotenuse of the triangle DEF is DF = 2a. |
What is the 30-60-90 Triangle rule?
30°-60°-90° Triangles In a 30°−60°−90° triangle, the length of the hypotenuse is twice the length of the shorter leg, and the length of the longer leg is √3 times the length of the shorter leg. To see why this is so, note that by the Converse of the Pythagorean Theorem, these values make the triangle a right triangle.
