Question

Adjacent, right angles are complementary. always, sometimes, or never

Answer 1

Adjacent right angles are Never complementary

Answer 2

What you'll need to answer this question are the definitions of adjacent, right angle, and complementary. For the sake of this question, I'll give you those definitions:

- Two angles are adjacent when they lie next to each other across a line. Imagine you have two line segments forming an angle, and that that angle is cut in half by another line segment, forming two smaller angles. Each of those smaller angles is adjacent to the other.
- A right angle is an angle formed at the meeting point of two perpendicular lines. For an example of what it means to be perpendicular, think of the angles a plus sign forms at each of its corners - those lines are what are called perpendicular.
- Complementary angles are two angles which add up to a right angle.

With this knowledge, take a look at the question again. Is it possible for two right angles that are next to each other to add up to another right angle? Can any number greater than zero, when added to itself, ever equal itself?
