How to solve 45
When given the length of the hypotenuse of a 45°-45°-90° triangle, you can calculate the side lengths by simply dividing the hypotenuse by √2. Note: Only the 45°-45°-90° triangles can be solved using the 1:1: √2 ratio method .
How do you find the missing side of a triangle?
Given two sides.
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).

Hypotenuse calculator
In a right triangle with cathetus a and b and with hypotenuse c , Pythagoras' theorem states that: a² + b² = c² . To solve for c , take the square root of both sides to get c = √(b²+a²) . This extension of the Pythagorean theorem can be considered as a "hypotenuse formula".
