Are complementary angles alwys adjacent?
Rectangles have congruent adjacent angles.
A pair of adjacent angles whose non-common sides are opposite rays are called a linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
If all adjacent angles are congruent, it can only be a rectangle (or square).
Two angles are adjacent if they have the same vertex, share a side and do not overlap. It is, therefore, perfectly possible for two obtuse angles to be adjacent. In fact, every pair of adjacent angles in a hexagonal tessellation (a honeycomb, for example), consists of a pair of obtuse angles (120 degrees).
No they are not because adjacent angles are on the same side while vertical angles are on the opposite therefore vertical angles are non adjacent.
When two lines intersect four angles are formed. Adjacent refers to angles that are next to each other so non adjacent refers to the ones opposite each other. They will have equal angles. Two adjacent angles in this situation will have a sum of 180 degrees.
Well, they're called vertically adjacent angles. They have the property that they are supplementary, because the non-adjacent sides form a straight line.
Verticle angles
Adjacent angles.
true
two adjacent angles formed by two intersecting tines are
Adjacent acute angle is not one word. An Adjacent angles are angles that are side by side.
The angles formed by one congruent side adjacent to the side not congrent to the first side
Supplementary
Adjacent angles are angles right next to each other
-- all four interior angles add up to 360 degrees-- any pair of adjacent angles adds up to 180 degrees-- the members of either pair of non-adjacent angles are equal
