Identify whether the given shapes are polygons. If not, give reasons?
(a) As the figure is not closed, therefore, the shape is not a polygon.
(b) As it is closed by line segments hence it is a polygon.
(c) As it is not made of line of segments it is not a polygon.
(d)As it has curved surface and also is made up of line of segments.
Name each polygon:
- b) Triangle
Give a sketch of a regular hexagon. Connecting its vertices, and by drawing a triangle. Identify the type of the triangle you have drawn.
123456 is a regular hexagon and triangle thus formed by joining 165 is an isosceles triangle.
Draw a rough sketch of a regular hexagon. Connecting any three of the given vertices, draw a regular triangle. Identify the type of the triangle you have drawn.
12345678 is a regular shaped octagon and 3456 is a regular shaped rectangle.
The line segment from the diagonal joins the any of two vertices in the polygon and is not in the side of the given polygon. Give rough sketch pentagons by drawing its diagonals.
12345 is the required pentagon and its diagonals are 1 4, 1 3, 2 5 and 2 4.
