Unit 4 Vocabulary Words (Math 7)
1.
Acute Angle
An angle measures less than 90o.
2.
Angle
The figure formed by two rays with a common
endpoints.
3.
Bisector
A point, (or segment, ray, or line) that divides
a segment or an angle into two congruent
parts.
4.
Congruent
Having the same size and shape
5.
Coordinate Plane
A plane formed by the intersection of
a horizontal number line called the
x-axis and a vertical line called a y-axis.
6.
Corresponding Angles
Matching angles of two or more polygons.
7.
Corresponding Sides
Matching sides of two or more polygons.
8.
Endpoint
Point at the end of a line segment or ray.
9.
Intersection
The point common to two or more geometric
figures. (The points where segments, rays and
lines intersect).
10.
Line
A straight path that extends without end in
opposite directions.
11.
Line Segment
A part of a line between two endpoints.
12.
Obtuse Angles
Angles that measures more than 90o but
less than 18o.
13.
Parallel Lines
Lines in a plane that do not intersect.
14.
Perpendicular Lines
Lines, line segments or rays that intersect to
form right angles.
15.
Plane
A perfectly flat surface that extends
infinitely in all directions.
16.
Point
An exact location in space. It is usually
represented as a dot, but it has no size at all.
17.
Ray
A part of a line that stars at one endpoint
and extends forever.
18.
Reflection
A transformation of a figure that flips the
figure across a line.
19.
Right Angle
An angle that measures exactly 90o.
20.
Rotation
A transformation in which a figure is
turned around a point.
21.
Symmetry
Correspondence of form and arrangement
of parts on opposite sides of a boundary,
such as a plane, line, or around a point or
axis.
22.
Transformation
A change in the position or orientation
of a figure.
23.
Translation
A movement (slide) of a figure along a
straight line.
24.
Triangle
A three sided polygon.
25.
Vertex
On an angle or polygon, the point where
two sides intersect.
Line symmetry – A figure has line symmetry if one-half is a mirror image of
the other half.
Rotational symmetry – A figure has rotational symmetry if it can be rotated
less than 360o around a central point and coincide
with the original figure.
