Polygon (how to name it): | Are 2-dimensional shapes. They are made of straight lines, andthe shape is "closed" (all the lines connect up) |
Side of a polygon: | A line segment connected to form |
Vertex of a polygon: | The point where 2 lines meet to form an angle and the corners of polygons and polyhedra are vertices |
Concave vs convex polygons: | Concave polygon is defined as a polygon with one or more interior angles greater than 180°. Convex polygon is defined as a polygon with all its interior angles less than 180° |
Regular polygon: | Is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex or star |
N-gon and other known polygons names: | Polygon with n sides |
Perimeter and Area of a triangle: | The distance around a two-dimensional shape. The size of a surface |
Perimeter and Area of a square: | The distance around a two-dimensional shape. The size of a surface |
Perimeter and Area of a rectangle: | The distance around a two-dimensional shape. The size of a surface |
