What is a 30 60 90 triangle?

What Is a 30-60-90 Triangle? A special right triangle with angles 30 , 60 , and 90 is called a 30-60-90 triangle. The angles of a 30-60-90 triangle are in the ratio 1 : 2 : 3. Since 30 is the smallest angle in the triangle, the side opposite to the 30 angle is always the smallest (shortest leg).

What is the meaning of 30 60 90 Triangle?

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. Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another.

What is the 30 60 90 formula for a triangle?

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.

What are the relationships between the sides and angles of triangles?

Relationship between sides and angles. In any triangle, the largest side and largest angle are opposite one another. In any triangle, the smallest side and smallest angle are opposite one another. In any triangle, the mid-sized side and mid-sized angle are opposite one another.
