How to solve
The side opposite the right-angle marker is the hypotenuse c. For a right triangle, a² + b² = c².
Steps
- Use the right-angle marker to identify the legs and hypotenuse.
- Substitute the two known side lengths.
- Solve for the missing positive length.
Example
A right triangle has legs 6 and 8.
- c² = 6² + 8² = 100.
- c = 10.
