Question

State if each triangle is a right triangle: *

13 in
2 in
12 in
​

Answer 1

It would be a obtuse triangle instead

Explanation:

By using pythagorean and theorem (a^2 + b^2 = c^2)

So it would be 13^2___2^2 + 12^2

When you square them, you get 169___4 + 144

144 + 4 = 148, which is less than 169

SO it would be 169>148

So no, not a right triangle
