Can a triangle have two right angles, and why or why not?
1 answer
No, a triangle cannot have two right angles. According to the properties of triangles, the sum of the three interior angles of a triangle is always 180 degrees. Therefore, if one angle is a right angle (90 degrees), then the sum of the other two angles must be 180 - 90 = 90 degrees. This means that the other two angles cannot be right angles, as their sum cannot exceed 90 degrees.
