What is an angle?
Made up of points with no thickenss or width.
What is a line?
The line that divides something into two equal parts
What is a bisector?
A measurable part of a line consisting of two endpoints.
What is a line segment?
Two angles with measures that sum to 90° (do not have to be adjacent)
What is complementary angles?
Location with no size or shape.
What is a point?
Points that lie on the same plane.
What is coplanar?
Two lines that intersect at a 90° angle (right angle) *symbol: ⊥*
What is perpendicular?
Two angles with measures that sum to 180° (do not have to be adjacent)
What is supplementary angles?
A flat surface made up of points and extends indefinitely in all directions.
Adjacent angles that are supplementary. Combined they form a straight line.
What is a linear pair?
A line that extends indefinitely in one direction.
What is a ray?
Two angles that share a common side and vertex
What is adjacent angles?
Two objects that have the same dimensions and shape
What is congruent?
Two angles directly across from each other on intersecting lines. (always congruent)
What is vertical angles?
Points that lie on the same line.
What is collinear?
