So all 3 angles in a triangle add up to 180. If B = 50, the other two angles would be 180-50 = 130. So that means that A + C = 130. I am using this info in every answer below.

An acute triangle is a triangle with three acute angles. An obtuse triangle is a triangle with one obtuse angle and two acute angles.Right triangles have a 90 degree angle.

1. Acute triangle means all angles are acute (less than 90).


So A + C =130.

So A and C could both be 65 degrees.

2. An obtuse angle is an angle which is greater than 90° and less than 180.

A + C = 130


So just say that C = 100 and A = 30.

3. A right triangle has a 90 degree angle.

A + C = 130

Let's say that A = 90 (to make it a right angle).

So that means C = 40.
