polygon • Simple closed figure formed by straight lines
Classified by # of sides! • 5 • 6 • 7 • 8 • 9 • 10
How many degrees are in each polygon? • There is a formula! • (n-2)(180)= • n = the number of sides
Regular polygon • All sides and angles are congruent • They are “equiangular” and “equilateral”
How do we find each angle of a regular polygon? • = this will be what just one angle of a regular polygon. • n= the number of sides
Example! • How many degrees does an angle in a regular hexagon have?
Tessellation • A repetitive pattern of polygons that fit together with no overlaps or holes • How do you know if you can make a tessellation? • The angle measurements Divide evenly into 360
