Question

A triangle has sides with lengths of 10 millimeters, 25 millimeters, and 28 millimeters, is it a right triangle

Answer 1

No, it is not a right triangle.

Explanation:

Let's take it as,

→ Hypotenuse = 28 mm

→ Perpendicular = 25 mm

→ Base = 10 mm

Now use Pythagoras theorem,

→ Hypotenuse² = Perpendicular² + Base²

→ 28² = 25² + 10²

→ 784 = 625 + 100

→ 784 ≠ 725

→ [ LHS ≠ RHS ]

Hence, it does not forms a right triangle.
