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
