Question

Can you still use the triangle sum Theorem even if a triangle is not in 180 degrees?

Answer 1

The sum of interior angles is 180 degrees (Triangle Angle Sum Theorem). All interior angles of a triangle are more than 0° but less than 180°.

Answer 2

Hi!

You cannot.

This is because ALL triangles MUST have 180 degrees, so if it doesn't it's not even a triangle. Therefore you cannot use it because, well, it's not a triangle.
