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.
