GEOMETRY ON THE STREETS!

POINT A point names a

location and has no size and is represented by a dot.

LINE (SEGMENT) A line segment is

a part of a line consisting of two points and all points between them.

PLANE

A plane is a flat surface that has no thickness and it extends forever.

ANGLE An angle is a

figure formed by two rays, or sides with a common endpoint.

PERPENDICULAR LINES Perpendicular

lines intersect at four 90 degree angles.

PARALLEL LINES Parallel lines are

coplanar and do not intersect.

TRIANGLE A triangle is a

closed plane figure having three sides and three angles.

RIGHT TRIANGLE A right triangle

is a triangle with one right angle.

PENTAGON A pentagon is a

polygon having five angles and five sides.

HEXAGON A hexagon is a

polygon having six angles and six sides.

SQUARE A square is a

rectangle having all four sides of equal length.

RECTANGLE A rectangle is a

four-sided plane figure with four right angles.

TRAPEZOID A trapezoid is a

quadrilateral plane figure having two parallel and two nonparallel sides.

PARALLELOGRAM A parallelogram

is a quadrilateral having both pairs of opposite sides parallel to each other.

CIRCLE A circle is a

closed plane curve consisting of all points at a given distance from a point within it called the center

CYLINDER A cylinder is a surface

or solid bounded by two parallel planes and generated by a straight line moving parallel to the given planes and tracing a curve bounded by the planes and lying in a plane perpendicular or oblique to the given planes.

SPHERE A sphere is a

solid geometric figure generated by the revolution of a semicircle about its diameter; a round body whose surface is at all points equidistant from the center.

OCTAGON An octagon is a

polygon having eight angles and eight sides.

POLYGON A polygon is a

figure, esp. a closed plane figure, having three or more, usually straight, sides.

EQUILATERAL TRIANGLE An equilateral

triangle is a three-sided regular polygon.
