Angles that add up to measure 180o
I think you mean octagon. The two types of angles are obtuse and acute angles.
When 2 lines intersect, 4 angles are formed. The angles that are directly opposite to each other are called opposite angles.
right angles are perpendicular lines that intercept each other at right angles which is 90 degrees
They follow one another such as consecutive or coresponding angles
when is the bsc supplementray exam of ou of 2009.
Adjacent angles are angles right next to each other
Complimentary angles are a pair of angles where the sum of their degrees equal 90.
Angles that add up to measure 180o
Two angles of a polygon that have a common side.
I think you mean octagon. The two types of angles are obtuse and acute angles.
it means that the angles are equal in degree measure
When 2 lines intersect, 4 angles are formed. The angles that are directly opposite to each other are called opposite angles.
at right angles to
Two supplementary angles add up to 180 degrees
Supplementary angles are angles that add up to 180 degrees
Do you mean the two angles that are formed by two intersecting lines? If yes, they are called vertical angles and they are congruent.
