Answer to Question #22291 in Geometry for rudy andrade
A triangle has side lengths of 10, 24, and 30. What type of triangle is it?
Let's use the Pythagorean Theorem:
a² + b² ? c².
If the left side is bigger, it's an acute triangle. If the right side is bigger, it's an obtuse triangle. If they are equal, it's a right triangle.
This one gives us
10² + 24² ? 30²,
676 < 900,
so it is an obtuse triangle.
