a. no, because there needs to be a third angle.
This is the correct response. A triangle is a polygon with three sides and three angles. The sum of the angles in a triangle is always 180 degrees. If a triangle has two right angles (90 degrees each), the sum of those angles would be 180 degrees. However, there would be no third angle left to complete the triangle, which is why a triangle cannot have two right angles.
Can a triangle have two right angles, and why or why not?
responses
