Convex and Concave Polygons - If all lines drawn across a polygon cut it in exactly 2 points, then it is convex ● ● ● ● ● ● - If one line drawn across it cuts it in more than 2 points, then it is concave ● ● ● ●

- If all sides and angles of a polygon are equal, then it is regular Regular and Irregular Polygons - If not all sides and angles of a polygon are equal, then it is irregular

It is the sum of the measures of the sides of the polygon Perimeter P= =46
