**Curve**

It is a shape or a line that is smoothly drawn in a plane that has a bent or turns in it. A circle is an example of a curved-shape. There are types of Curves such as:

(i) Simple Curve: A curve that transforms its direction but it does not intersect itself is called a simple curve. It may be open or closed.

(ii) Non-Simple Curve: The curve that intersects itself while changing its direction is known as the Non-Simple Curve.

(iii) Open Curve: A curve that has 2 endpoints & when it does not enclose the area within itself it is called an open curve.

(iv) Closed Curve: It has no endpoints & when it encloses the region or area will form.

**Polygon**

It is a closed figure built of line segments not curves in a two-dimensional plane. At least 3 line segments are needed to link end to end to create a closed figure. Therefore, a polygon with at least 3 sides is called Triangle & it is also known as 3-gon. An n-sided polygon is known as n-gon.

**Regular Polygon**

If each side & interior angle of the polygon is equal, it is called a regular polygon. Examples of regular polygons are rhombus, square, equilateral triangle, etc.

**Irregular Polygon**

If each side & the interior angle of the polygon are of different measure, it is called an irregular polygon. The examples of irregular polygons are a rectangle, a scalene triangle a kite, etc.** **

**Properties of polygons are based on their sides & angles**
(i) The sum of all the interior angles of an n-sided polygon is (n – 2) × 180°.

(ii) The number of diagonals in a polygon with n sides = n(n – 3)/2

- (iii) The number of triangles builds by joining the diagonals from one corner of a polygon = n – 2

- (iv) The measure of each interior angle of n-sided regular polygon = [(n – 2) × 180°]/n

- (v) The measure of each exterior angle of an n-sided regular polygon = 360°/n
