Geometry
linear pair
A linear pair of angles is formed when two lines intersect.
linear pair
A pair of adjacent angles whose noncommon sides are opposite rays.
Vertical angles
A pair of opposite congruent angles formed by intersecting lines
Vertical angles
The angles opposite each other when two lines cross. Vertical in this case means they share the same vertex
linear pair
The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 angles
Complementary angles
There has to be two angles that equal up to 90 degrees but they don't have to be by each other though
supplementary angles
They don't have to be next to each other,just so long as the total is 180 degrees
complementary angles
Two Angles are Complementary when they add up to 90 degrees (a Right Angle).
linear pair
Two angles are a linear pair if they have a common side and their other sides are opposite rays
Vertical angles
Two angles directly across from each other on intersecting lines
supplementary angles
Two angles whose sum is 180 degrees
Complementary angles
Two angles whose sum is 90 degrees
supplementary angles
the two angles must either both be right angles, or one must be an acute angle and the other an obtuse.
linear pair
two adjacent angles whose noncommon sides are opposite rays
supplementary angles
two angles that add up to 180 degrees
Complementary angles
two angles that add up to 90 degrees
supplementary angles
two angles whose measures have a sum of 180 degrees
Complementary angles
two angles whose measures have a sum of 90 degrees
Vertical angles
two angles whose sides form two pairs of opposite rays
Vertical angles
two nonadjacent angles formed by two intersecting lines
