Question

Can a triangle have two right angles?

Open in App

Solution

As the sum of the interior angles in a triangle always must be $180$ degrees, If there are two right angles in a triangle then the sum would exceed 180 which is not possible.
Hence, we cannot have two right angles in a triangle.
