Point

• An undefined term in geometry. It names a location and has no size.

• *Registration and inspection stickers on a windshield are examples of points on a plane.

Line Segment• A part of a line consisting of two endpoints and all points

between them.

Page 4: Geometry In The Real World

Plane

• A flat surface that has no thickness and extends forever.

Page 5: Geometry In The Real World

Angle

• A figure formed by 2 rays, or sides, with a common endpoint.

Page 6: Geometry In The Real World

Perpendicular lines

• Lines that intersect at 90 degrees.

Page 7: Geometry In The Real World

Parallel Lines •Coplaner lines that do not intersect.

Page 8: Geometry In The Real World

Triangle• A 3-sided shape whose angles add up to

180 degrees.

Page 9: Geometry In The Real World

Right triangle

• A triangle with one right angle.

Pentagon

Car windows are sometimes pentagons.

•A five sided polygon.

Hexagon

• A six-sided polygon.

Square

• A quadrilateral with four congruent sides and four congruent angles.

Page 13: Geometry In The Real World

Rectangle

• A quadrilateral with four right angles.

Trapezoid

• A quadrilateral with exactly one pair of parallel sides.

Page 15: Geometry In The Real World

Parallelogram• A quadrilateral with two pairs of parallel

sides.

Circle

•The set of points in a plane that are a fixed distance from a given point called the center of the circle.

Page 17: Geometry In The Real World

Cylinder

• A three-dimensional figure with two parallel congruent circular bases and a curbed lateral surface that connects the bases.

Page 18: Geometry In The Real World

Sphere• The set of points in space that are a fixed

distance from a given point called the center of the sphere.

Octagon• An eight-sided polygon.

Page 20: Geometry In The Real World

Oval

• A closed plane curve resulting from the intersection of a circular cone and a plane cutting completely through it.

Skew Lines

• Lines that are not coplaner.
