Obtuse triangle

Step-by-step explanation:

For right triangle: check if 10²+12²=16²:

10²+12²=100+144=244 not equal to 16²=256.

So no 90⁰ in this triangle.

If we apply the cosine theorem:

16²=10²+12²-2×10×12×cos(A), cos(A) should be < 0 so that 10²+12²+something=16².

So the angle A >90 (its cosine<0), the triangle is obtuse.

Obs: A is the angle opposed to side of 16
