Answers
Answer:
1. Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap. they have a common side (line CB) ...
they have a common vertex (point B)
2. Two Angles are Complementary when they add up to 90 degrees (a Right Angle).
They don't have to be next to each other, just so long as the total is 90 degrees.
60° and 30° are complementary angles.
3. An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees.
However, A reflex angle measures more than 180 degrees but less than 360 degrees.
4. Unequal supplementary angles means sum of angles is 180∘ and supplement angles are unequal.
5. Acute angles are less than 90 degrees, obtuse angles are more than 90 degrees, and right angles are exactly 90 degrees.
