Question

Which of the following triangles is the right triangle?
Answer
A. 4, 4, 4
B. 18, 19, 35
C. 16, 63, 65
D. 9, 12, 20

Answer 1

If \(c^{2} = a^{2} + b^2\), then it's a right triangle.
If \(c^2 > a^2 + b^2\), then it's an obtuse triangle.
If \(c^2 < a^2 + b^2\), then it's an acute triangle.

Answer 2

Use the Pythagorean Theorem which is a^2 +b^2=c^2
c=the largest number in the set.
a + b are the other two numbers.
*if the numbers equal each other on both sides of the equation it is the right triangle.
