A point on a plane

Page 1

A line that is bounded by two distinct end points

Page 2

A plane is a flat, two-dimensional surface.

Page 3

Intersecting Lines
Two or more lines that meet at a point.

Page 4

Vertical Lines
A vertical line is one the goes straight up and down, parallel to the y-axis of the coordinate plane.

Horizontal line

A straight line on the coordinate plane where all points on the line have the same y-coordinate.

Acute angle
An angle that measures less than ninety degrees but more than zero degrees

Page 6

Obtuse angle
An angle that measures more than 90 degrees but less than 180 degrees

Page 7

Right angle
An angle that bisects the angle formed by two halves of a straight line

Page 8

A rectangle in which two adjacent sides have equal length.

Page 9

A rectangle is any quadrilateral with four right angles

Page 10

A shape with no straight lines.

Page 11

Parallel lines
Are lines in a plane which do not meet

Page 12

Any three points, when non-collinear

Page 13

A semicircle is a one-dimensional locus of points that forms half of a circle.

Page 14

 A three-dimensional solid object bounded by six square faces

Page 15

A decagon is any polygon with ten sides and ten angles.

Page 16

A polygon with six edges and six vertices.

Page 17

A polygon all of whose sides are the same length and all of whose interior angles are the same measure.

Page 18

A pentagon is any five-sided polygon.

Page 19

Intersecting Lines
Two or more lines that meet at a point.

Page 20

Vertical angles
Have a common vertex, but they are never adjacent angles
