2.5 – How Can I See It?______________ Classify Polygons In this section you will discover the names of the many different polygons and how they are classified.

3
Polygon: 2. No sides overlap 3. No curved sides 1. Has at least 3 sides

4
Side: Line segment forming the polygon M T S R Q

5
Vertex: Point where two sides meet M T S R Q M T S R Q

6
Consecutive Sides: Two sides that share a point, one after the other M T S R Q

7
Diagonal: Segment that joins two nonconsecutive sides M T S R Q

8
# of sidesName 3 4 5 triangle quadrilateral pentagon

9
# of sidesName 6 7 8 9 10 11 12 13 n hexagon heptagon octagon nonagon decagon 11-gon dodecagon n-gon 13-gon

10
Convex: No corners point inside the shape Concave: Not convex! A corner points inside the shape
