Question

Consider a triangle with side lengths of 10 ft, 17.32 ft, and 20 ft. By examining the side lengths, what can you conclude about the measurement of the angles? Explain your reasoning. \

Answer 1

One of the angles in this triangle must be a right angle.

Explanation:

Looking at the sides of the triangle, these work in the Pythagorean theorem:

10²+17.32² = 20²

100+299.9824 = 400

399.9824 = 400

The difference between the numbers is due to rounding. Since they work, this is a right triangle; one of the angles must be a right angle.

Answer 2

That it is an scalene triangle since all the sides are different lengths. I don't really know what you are looking for but I hope this helps.
