Question

A triangle has sides with length of 12 miles 16 miles 20 miles Is it a right triangle

Answer 1

Answer:

Yes! This is a right triangle.

Step-by-step explanation:

To solve this problem, you need to use the Pythagorean Theorem, which is: $a^2+b^2=c^2$. In this equation, "A" represents the smallest length, "B" represents the next smallest length, and "C" represents the largest length. If a triangle is a right triangle, then the A squared + B squared equals C squared.

In this equation:

A = 12

B = 16

C = 20

 1. Insert the values: $12^2+16^2=20^2$

               2. Simplify: $144+256=400$

                                   $144+256=400$, and $20^2=400$, so this is a right triangle.
