100
------ two dimensional figure with three or more sides, where each side meets exactly two other sides at their endpoints.
Polygon
100
Point, Line, and Plane
Undefined Terms
100
given 2 points A and C, a third point B lies on the line segment AC if and onlyif the distances between the points satisfy the equation AB + BC = AC
Segment Addition Postulate:
100
is formed by two rays with the same endpoint.
Angle
100
Angles that are next to each other.
Adjacent angles
200
A 2D diagram that you can fold to form 3D figure.
Net
200
-----has no dimension. .
a point
200
a point that divides the segment into two congruent segments.
Midpoint
200
Measures greater than 0 and less than 90
Acute angle
200
Two angles whose measures have a sum of 90 °. Example:
Complimentary angles
300
Corner view of a 3D figure.
Isometric Drawing
300
looks like a floor or a wall, but it extends without end.
Plane
300
A point, line, ray, or other segment that intersects a
segment at its midpoint is said to bisect the segment.
Segment Bisector
300
Measures greater than 90 and less than 180
Obtuse angle
300
Two angles whose measures
have a sum of 180 °
Supplementary
400
three separate views , a
top view, a front view, and a right side view.
Orthographic drawing
400
Points that lie on the same line
Collinear
400
part of a line that consists of two
endpoints and all points between them.
Segment
400
states that If point B is in the interior of ∠ AOC, then m
∠ AOB + m ∠ BOC = m ∠ AOC.
Angle Addition Postulate
400
is a pair of adjacent angles whose noncommon sides are opposite rays. The angles of a linear pair form a straight angle.
Linear Pair
500
What is a net for the figure? Label the net with its
500
Points and lines that lie in the same plane
Coplaner
500
The distance between points A and B is the
absolute value of the difference of their coordinates, or |a – b|.
This value is noted by AB, or the length between A and B
Ruler Postulate
500
if m A = m ∠ B, then ∠ A = ∠ B. are called __________ angles
congruent
500
a ray that cuts an angle in half equally.
Angle Bisector
