Points, Lines, Planes, and Angles Vocabulary
Terms in this set (23)
Equidistant
equally distant
Point
simplest figure studied in geometry
Line
a figure with no thickness that extends in two directions without ending
Plane
a figure with no thickness or edges, yet extends without ending
Space
the set of all points
Collinear Points
all the points in one line
Coplanar Points
points all in one plane
Intersection
the set of points in both figures where the two meet
"Between"
collinear, falling on the same line, and somewhere on the line between the two points
"Congruent"
two objects that have the same size and shape, symbol is a = with a ~ over the top
midpoint of a segment
the point that divides a line segment into TWO CONGRUENT line segments.
bisector of a segment
the line, segment, ray, or plane that INTERSECTS the segment at its MIDPOINT.
Angle
figure formed by 2 rays that share a common endpoint
Vertex
that common endpoint
Sides
2 rays of the angle
Protractor
tool used to measure the degree of an angle °
Congruent Angles
angles of equal measure
Adjacent Angles
2 angles in a plane that have a common vertex and a common side
Bisector of an Angle
ray that divides an angle into 2 congruent , adjacent angles
Ruler Postulate
The points on a line can be corresponded to real numbers anyhow to a way where two points can be 0 and 1. Once a coordinate system is set up that way, the distance between any two points is the absolute value of the difference of their coordinates/points.
Segment Addition Postulate
On line segment ABC, if B is between A and C, then AB + BC = AC
Protractor Postulate
You can measure an angle from any angle.
Angle Addition Postulate
<ABC = <ABD + <DBC
