Answer:
Yes! This is a right triangle.
Step-by-step explanation:
To solve this problem, you need to use the Pythagorean Theorem, which is: [tex]a^2+b^2=c^2[/tex]. 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: [tex]12^2+16^2=20^2[/tex]
2. Simplify: [tex]144+256=400[/tex]
[tex]144+256=400[/tex], and [tex]20^2=400[/tex], so this is a right triangle.
