Question

Work

Determine whether each triangle with sides of given lengths is a right
triangle. Justify your answer. (Example 3)
30 cm, 122 cm, 125 cm
5

Answer 1

It is not.

Explanation:

The formula of a right triangle is "
`a^(2)+b^(2) =c^(2)`" where c is the hypothenuse (the longest side of the triangle) if we replace the formula with the values we will get

"
`30^(2) +122^(2) =125^(2) \\900 + 14884 = 15625\\15784\\eq 15625`
