### Important Discussions in the Chapter

• Lines are straight paths which have length but no width. Any two points on it can be joined to make a segment called line segment or simply line.

• A ray is half of a line, i.e., only the part lying between the starting point and ending point is considered as ray while the rest of it will not be considered as ray. Any point on the line is considered as a vertex of the angle formed by two rays.

• A segment can be defined as part of a line which has both its endpoints lying on that particular line only.

• An open figure or shape is one in which interior points are not included while closed figures or shapes have interior points as well.

• A polygon is a closed figure which is made up of line segments and has at least three sides. The sum of the measures of all angles in a polygon is 1800.

• Triangles are polygons with three sides and three angles. The sum of the measures of two opposite angles in a triangle is 1800 and the sum of measures of any two angles in a triangle is equal to 1800.

• A quadrilateral has four sides and at least four angles also called a ‘quadrangle’. The sum of all exterior angles formed by joining consecutively each vertex with consecutive vertices (without including the angle formed by the first and last vertex) is 3600.

• A circle is a closed figure with no ends or corners which can be defined as the set of all points in a plane which are equidistant from a fixed point called centre. The distance between any two points on the circumference of the circle is called radius.
