The key characteristic of a 30 60 90 right triangle is that its angles have measures of 30 degrees p6 rads 60 degrees p3 rads and 90 degrees p2 rads. It is right triangle whose angles are 300 600 and 900. Since this triangle is half of an equilateral triangle some refer to this as the hemieq triangle.

Properties of a 30 60 90 right triangle a special kind of triangle.
Special triangle 30 60 90 side lengths. Special right triangles 30 60 90. The hypotenuse is the longest side in a right triangle which is different from the long leg. What are special right triangles. Because it is a special triangle it also has side length values which are always in a consistent relationship with one another.
The following diagram shows a 30 60 90 triangle and the ratio of the sides. The side lengths of a 30 60 90 triangle this is a triangle whose three angles are in the ratio 123 and respectively measure 300 600 and 900. Two of the most common right triangles are 30 60 90 and the 45 45 90 degree triangles. Sides with integer lengths but almost isosceles.
Scroll down the page for more examples and solutions on how to use the 30 60 90 triangle. Angle based special right triangles are specified by the relationships of the angles of which the triangle is composed. The side lengths are generally deduced from the basis of the unit circle or other geometric methods. The long leg is the leg opposite the 60 degree angle.
The sides of a 30 60 90 right triangle lie in the ratio 132. 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. 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. A 30 60 90 right triangle is a special right triangle in which one angle measures 30 degrees and the other 60 degrees.
Sides with integer lengths called pythagorean triplets. The angles of these triangles are such that the larger right angle which is 90 degrees or p 2 radians is equal to the sum of the other two angles. 345 51213 81517 72425 94041. Special right triangle 300 600 900 is one of the most popular right triangles.
The triangle is significant because the sides exist in an easy to remember ratio. The lengths of the sides of a 300 600 900 triangle are in the ratio of 132. Right triangle the sides of which are in a geometric progression kepler triangle. That is to say the hypotenuse is twice as long as.
A 30 60 90 right triangle literally pronounced thirty sixty ninety is a special type of right triangle where the three angles measure 30 degrees 60 degrees and 90 degrees. All 30 60 90 triangles have sides with the same basic ratio. Because it is a special triangle it also has side length values which are always in a consistent relationship with one another.
