## How do you find the third side of an equilateral triangle?

**Correct answer:**

- The height splits the triangle’s base in half and creates two right triangles. Create expressions for the length of the two unknown sides in this new triangle: …
- Use the Pythagorean Theorem to find the value of or the side length: …
- Multiply the side length you found by 3 to get the perimeter:

## How do you find the missing side of a triangle?

**How to find the sides of a right triangle**

- if leg a is the missing side then transform the equation to the form when a is on one side and take a square root: a = √(c² – b²)
- if leg b is unknown then. b = √(c² – a²)
- for hypotenuse c missing the formula is. c = √(a² + b²)

## How do you find a hypotenuse?

The hypotenuse is termed as the longest side of a right-angled triangle. To find the longest side we use the hypotenuse formula that can be easily driven from the Pythagoras theorem (Hypotenuse)^{2} = (Base)^{2} + (Altitude)^{2}. Hypotenuse formula **= √((base) ^{2} + (height)^{2}) (or) c = √(a^{2} + b^{2})**.
