False. By definition, supplemental angles add up to 180 degrees. The interior angles of a triangle add up to 180 degrees. There are 3 interior angles in a triangle; therefore no two angles in a triangle can ever be supplemental whether it is a right triangle or not.
This is a bit of a trick question to see if you know the difference between supplemental angles and complementary angles because the acute angles in a right triangle are complementary. By definition, complementary angles add up to 90 degrees. A right triangle has one 90 degree angle; therefore, the remaining two angles must add up to 90 degrees.
