Polygons by daniela https://padlet.com/d_wright/rp7q9ojkxwie en-us 2014-05-01 01:06:37 UTC 2025-12-02 21:58:44 UTC hello@padlet.com The  Types of Polygons d_wright https://padlet.com/d_wright/rp7q9ojkxwie/wish/27645052
  • Convex- All diagonals will be drawn inside the figure (every interior angle will be less than 180°)
  • Concave- Possible to draw diagonals outside the figure ( at least one interior angle is more than 180°)
  • Regular- A polygon with congruent sides and angle
  • Similar- Polygons with congruent corresponding angles and
    • corresponding sides in proportion
            • Similar Polygons have similarity ratios (the ratio of two corresponding sides)

    *If You Forgot*

    A diagonal is a segment connecting two corners/vertices of a figure.

    A polygon is a closed figure with at least 3 sides that are segments;

    the sides only intersect at their endpoints.

    • Individual Interior Angle: (n−2) x 180 ÷ n
    Sum of Exterior Angles: ALWAYS 360
    • Individual Exerior Angle: 360 ÷ n
    **n represents the number of sides in a Polygon**

    Area of a Regular Polygon: A =½ ap

    **a represents the apothem (a line that connects the center point to a side at a right angle and bisects that side length**

    **Important To Note**

    All sides must have the same similaritiy ratio:

    5/10 = 2/4 = 3/6 =1/2
