What is a Polygon? • Closed figure • Connecting line segments • Each line segment meets at an endpoint
Which ones are polygons? B. A. C. D. E.
Regular Polygon • Sides are all of equal length • Angles are all equal
Triangle • Three-sided polygon • The sum of all the angles is 180° Obtuse Acute Equilateral Scalene Isosceles Right
Quadrilateral • Four-sided • The sum of all the angles is 360°
Rectangle • Four-sided • All angles are 90° • The sum of all the angles is 360°
Square • Four-sided • Equal-length sides • All right angles • The sum of all the angles is 360°
Parallelogram • Four-sided • Two pairs of parallel sides • The sum of all the angles is 360°
Rhombus • Four-sided • Equal-length sides • The sum of all the angles is 360°
Trapezoid • Four-sided • Exactly one pair of parallel sides • Bases • The sum of all the angles is 360°
Pentagon • Five-sided • The sum of all the angles is 540°
n-gon • n-gon is a polygon with n sides Hexagon Heptagon Decagon Octagon
