Can a triangle have two right angles, and why or why not?(1 point) Responses No, because there needs to be a third angle. No, because there needs to be a third angle. Yes, because it would be a right triangle. Yes, because it would be a right triangle. Yes, because 90 + 90 = 180. Yes, because 90 plus 90 equals 180 . No, because a triangle must have an obtuse angle. No, because a triangle must have an obtuse angle.

Answer 1

The correct answer is: No, because there needs to be a third angle.

A triangle can only have a total angle sum of 180 degrees. If a triangle had two right angles (each 90 degrees), the sum of those two angles would be 180 degrees, leaving no degrees for a third angle, which is not possible. Therefore, a triangle cannot have two right angles.
