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

Correct answer:
  1. 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: …
  2. Use the Pythagorean Theorem to find the value of or the side length: …
  3. 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
  1. 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)
  2. if leg b is unknown then. b = √(c² – a²)
  3. for hypotenuse c missing the formula is. c = √(a² + b²)
