Points, Lines, Planes, and Angles Vocabulary
Terms in this set (23)
simplest figure studied in geometry
a figure with no thickness that extends in two directions without ending
a figure with no thickness or edges, yet extends without ending
the set of all points
all the points in one line
points all in one plane
the set of points in both figures where the two meet
collinear, falling on the same line, and somewhere on the line between the two points
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.
figure formed by 2 rays that share a common endpoint
that common endpoint
2 rays of the angle
tool used to measure the degree of an angle °
angles of equal measure
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
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
You can measure an angle from any angle.
Angle Addition Postulate
<ABC = <ABD + <DBC
