Question

Verify this triangle is a right triangle:
a = 12
b = 7
C = 15

Answer 1

No

Explanation:

Formula is a squared + b squared = c squared

12 times 12 = 144

7 times 7 = 49

144 + 49 = 193

so 15 times 15 should = 193

but 15 times 15 = 225

Answer 2

This triangle is not a right triangle

Explanation:

If it were a right triangle, then the pythagorean theorum would work

a^2 + b^2 = c^2

12^2 + 7^2 = 15^2

144 + 49 = 225

This is not true because 144+49=193, not 225

So this triangle is not a right triangle
