Adjacent angles are when the 2 angles have a common vertex and a common arm.

if the exterior sides of 2 adjacent angles are perpendicular, then the angles are complementary angles.

Then the sum of the 2 adjacent angles is a right angle – 90u00b0.

When 2 angles add upto 90u00b0, they are called a pair of complementary angles.

Answer:## Complementary

Step-by-step explanation:If the exterior sides of two adjacent angles are perpendicular, then the angles arecomplementaryangles.The statement is defining two adjacent triangles that are on a right angles, that is, a angle equal to 90u00b0. We can deduct this because they problem states that their exterior sides are perpendicular, these sides are forming a right angle, because that’s what perpendicularity means.

Therefore, the right term that completes the statement is “complementary”, because complementary angles are define as adjacent angles which sum is 90u00b0.
