The variable

*stands for the*

**A and B***in a right triangle.*

**legs***, on the other hand stands for the*

**C***, which is the longest line in a triangle.*

**hypotenuse**The Pythagorean Relationship is formula that we use to find a side length in a given triangle.

It means that when you add the area of leg A and the area of leg B, the sum would be the area of the hypotenuse,C.

2. Solve for the missing side length.

**No, it's not a right triangle because**

**the formula(Pythagorean relationship)**

**says that a² + b² = c² but**

**when you sum up the leg A and B(8² + 6²)**

**the answer is 100cm² and not 121cm² which**

**is the area of the given measurement(11 cm) in hypotenuse.**
