## How do you find the side of a triangle with an angle and a side?

**In any right angled triangle, for any angle:**

- The sine of the angle = the length of the opposite side. the length of the hypotenuse.
- The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
- The tangent of the angle = the length of the opposite side. the length of the adjacent side.

## Can you solve a triangle with only 2 sides?

SAS. This means we are given two sides and the included angle. For this type of triangle, we must use The Law of Cosines first to calculate the third side of the triangle; then we can use The Law of Sines to find one of the other two angles, and finally use Angles of a Triangle to find the last angle.

## What are the formulas for triangles?

A triangle with one right angle. C = A + B = Pi/2 radians = 90o c2 = a2 + b2 (Pythagorean Theorem) | |

P = a + b + c s = (a+b+c)/2 K = ab/2 ha = b hb = a hc = ab/c ma = sqrt(4b2+a2)/2 mb = sqrt(4a2+b2)/2 mc = c/2 |
