Block (4)

PointA geometric element that has zero

dimensions and a location determinable by an ordered set of coordinates.

Line (Segment)The portion of a line that lies strictly between

two point.

PlaneA two-dimensional group that goes infinitely

in all directions.

AngleThe union of two rays that have a common

endpoint. Angles are measured in degrees.

Perpendicular LinesTwo segment rays , or lines that intersect two

form 90 degree angles.

Parallel LinesTwo or more co-planer lines that have no

points in common and never intersect.

TriangleA polygon with three sides whose angles add

up to 180 degrees.

Right TriangleA triangle with that has an angle of 90

degrees.

PentagonA five-sided polygon

Hexagon A six-sided polygon.

SquareAn equilateral and equiangular quadrilateral.

RectangleA quadrilateral whose angles are all right

angles.

Trapezoid A quadrilateral with at least one pair of

parallel lines and a pair of intersecting lines.

ParallelogramA quadrilateral with both pairs of opposite

side parallel.

Circlethe set of points on a plane at a certain

distance radius from a certain point center; a polygon with infinite sides.

CylinderA solid bounded by two parallel planes and

such a surface, especially such a surface having a circle as its base.

SphereThe set of points in space equidistant from a

certain point

OctagonAn eight-sided polygon

ConeThe surface of a conic solid whose base is a

circle.

Acute AngleAn angle whose measure is greater than 0

but less than 90 degrees.
