Explanation:
Triangles which have two legs and a hypotenuse are called right triangles. Right triangles have a special relationship between their sides called the Pythagorean Theorem. If a = 3 and b= 3, then find c using the Pythagorean theorem below.
![a^2+b^2=c^2\\3^2+3^2 = c^2\\9+9=c^2\\18 = c^2\\c=√(18) =3√(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/unhl58dr2ufrw40dofwaikreh8gx1bgngk.png)
