triangle abc is a right triangle.\nwhat is the relationship between angles a and b?\n○ they are congruent.\n○ they are complementary.\n○ they are supplementary.\n○ there is no relationship between them.

Answer

Brief Explanations:

In a right triangle, the sum of the two non - right angles is equal to (90^{\circ}) (since the sum of all angles in a triangle is (180^{\circ}) and one angle is (90^{\circ})). Angles A and B are the non - right angles of right triangle ABC. We can also check by adding their measures: (59^{\circ}+31^{\circ} = 90^{\circ}). Complementary angles are defined as two angles whose sum is (90^{\circ}), so angles A and B are complementary.

Answer:

They are complementary.
