Can a right triangle have a 140 degree angle? - Answers

No, not really. The two remaining interior angles have to add up to 90, since the sum of the angles in a triangle must total 180. The right angle means you have already used 90, so the remaining two must have a sum of 90. There is a more complex answer. Right triangles can have an external angle of 140. If angle A is 90 degrees, and angle B is 40 degrees, then angle C will be 50 degrees. The external angle at the extension of AB, through corner B, namely the extension of a ray from A through B, will create an angle with segment CB. It will be the sum of the measures of A and C: 140 degrees.
