# What formula is used for non-right triangles?

## What formula is used for non-right triangles?

The Law of Sines can be used to solve oblique triangles, which are non-right triangles. According to the Law of Sines, the ratio of the measurement of one of the angles to the length of its opposite side equals the other two ratios of angle measure to opposite side.

### How do you find the angle of a non-right triangle with two sides?

Use variables to represent the measures of the unknown sides and angles. Apply the Law of Cosines to find the length of the unknown side or angle. Apply the Law of Sines or Cosines to find the measure of a second angle. Compute the measure of the remaining angle.

**What is the formula for calculating angles?**

The formula for finding the total measure of all interior angles in a polygon is: (n – 2) x 180. In this case, n is the number of sides the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.

**Can you use Sohcahtoa on non-right triangles?**

For right-angled triangles, we have Pythagoras’ Theorem and SOHCAHTOA. However, these methods do not work for non-right angled triangles. For non-right angled triangles, we have the cosine rule, the sine rule and a new expression for finding area.

## Does Sohcahtoa work for all triangles?

Q: Is sohcahtoa only for right triangles? A: Yes, it only applies to right triangles. If we have an oblique triangle, then we can’t assume these trig ratios will work. We have other methods we’ll learn about in Math Analysis and Trigonometry such as the laws of sines and cosines to handle those cases.

### Can you use Sohcahtoa on non right triangles?

**Can you use Pythagoras on a non right angled triangle?**

Pythagoras’ theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.

**Is a 2 B 2 C 2 only for right triangles?**

Pythagorean theorem: If a triangle is a right triangle (has a right angle), then a2+b2=c2. Converse: If a2+b2=c2 in a triangle with c is the longest side, then a triangle is a right triangle. If a triangle is not a right triangle, there are 2 other options for types of triangles.

## Can you use Pythagorean theorem on a non right triangle?

The Generalized Pythagorean Theorem is the Law of Cosines for two cases of oblique triangles: SAS and SSS. Dropping an imaginary perpendicular splits the oblique triangle into two right triangles or forms one right triangle, which allows sides to be related and measurements to be calculated.
