Slide 1

Geometry Vocabulary

Mr. Fiore

&

Mr. Ryan

Slide 2

Geometry is the study of shapes

They studied Geometry in Ancient Mesopotamia & Ancient Egypt

Geometry is important in the art and construction fields

Slide 3

A POINT is an exact location on a graph, shape or in “space”.

The Hershey Kiss is a POINT on the line

●

Slide 4

A LINE goes in opposite directions and never, never, never ends.

Imagine if this Twizzler went on forever and ever and ever and ever and ever and ever

Slide 5

A RAY is part of a line, but it has one endpoint and the other end keeps going.

●

Slide 8

A VERTEX is a fancy name for “angle”

Two rays or lines that have the same endpoint make a VERTEX/angle

VERTEX/angles are measured in “degrees”

The Corners of a square are its vertex/angles

When two lines cross, they make vertex/angles

Slide 9

CONGRUENT means the “same”

CONGRUENT LINE SEGMENTS means two line segments are the same

CONGRUENT Vertex/Angles means two angles are the same

The Hershey & Crunch Bar are a Congruent size

Slide 10

A VERTICAL LINE goes up & down

The candy bars are vertical

Slide 11
