Lessons 12.1 and 12.3

Describe Plane Shapes and

Identify PolygonsSlide2

Lesson Opening

In your math notebook describe (using words) the two shapes below.Slide3

Plane Shapes

Both of these shapes are

PLANE SHAPES

or

shapes on a flat surface.Slide4

Closed Shapes

This is a closed shape, or a

shape that starts and ends at the same point

.Slide5

Closed Shapes

These are all closed shapes.Slide6

Open Shapes

This is an open shape, or a shape that

does NOT start and end at the same point.Slide7

Open Shapes

These are all open shapes.Slide8

Polygons

Some closed shapes are made up of only line segments. These shapes are called polygons.Slide9

Polygons

Some closed shapes are made up of only line segments. These shapes are called polygons.

This polygon has 5 line segments.

Polygons

A closed shape that is made up only of line segments.

A

triangle

is a polygon with 3 sides

(or 3 line segments).

A

quadrilateral is a polygon with 4 sides (or 4 line segments).A

pentagon is a polygon with 5 sides (or 5 line segments).A hexagon

is a polygon with

6 sides

(or 6 line segments).

A

octagon

is a polygon with

8 sides

(or 8 line segments).Slide16
