30 60 90 triangle ratio math. A 30 60 90 triangle has fairly simple sines cosines and tangents for each angle and these measurements will always be consistent. 30 60 90 triangles another type of special right triangles is the 30 60 90 triangle. In a 30 60 90 triangle the sides are in the ratio 1. The lengths of the sides of a 30 60 90 triangle are in the ratio 1 3 2 side1.

Like the 30 60 90 triangle knowing one side length allows you to determine the lengths of the other sides. This is right triangle whose angles are 30 60 and 90. There are two special triangles in trigonometry. We will prove that below.

Scroll down the page for more examples and solutions on how to use. The lengths of the sides of a 30 60 90 triangle are in the ratio of 1 3 2. A 30 60 90 triangle is a right triangle where the three interior angles measure 30 60 and 90. Knowing your 30 60 90 triangle rules will be able to save you time and energy on a multitude of different math problems namely a wide variety of geometry and trigonometry problems.

Geometry proper understanding of 30 60 90 triangles will allow you to solve geometry questions that would either be impossible to solve without knowing your ratio rules or at the very least would take. In the study of trigonometry the 30 60 90 triangle is considered a special triangle knowing the ratio of the sides of a 30 60 90 triangle allows us to find the exact values of the three trigonometric functions sine cosine and tangent for the angles 30 and 60. Right triangles with 30 60 90 interior angles are known as special right triangles. The most important rule to remember is that this special right triangle has one right angle and its sides are in an easy to remember consistent relationship with one another the ratio is a.

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. The other is the isosceles right triangle. 30 60 90 triangle rules and properties. The triangle is significant because the sides exist in an easy to remember ratio.

It is right triangle whose angles are 30 60 and 90. For example sin 30 read as the sine of 30 degrees is the ratio of the side opposite the. 30 60 90 triangle in trigonometry. Special triangles in geometry because of the powerful relationships that unfold when studying their angles and sides.

The following diagram shows a 30 60 90 triangle and the ratio of the sides. Memorizing and understanding the 30 60 90 triangle ratio will also allow you to solve many trigonometry problems without either the need for a calculator or the need to approximate your answers in decimal form. The 45 45 90 triangle also referred to as an isosceles right triangle since it has two sides of equal lengths is a right triangle in which the sides corresponding to the angles 45 45 90 follow a ratio of 1 1 2. One is the 30 60 90 triangle.
