GEOMETRY Point: A point is a basic idea in geometry. It shows a definite location or position. It is denoted by a dot. It has no length, breadth or thickness. It is named by a capital letter. Line Segment: The shortest distance between two fixed points is called a line Segment. The two points of line segments are called end points. A line segment is drawn with the help of a ruler and a pencil. 1. A line segment has two points on it. 2.A line segment has only length and no thickness or breadth. Line: Take a line segment AB. Extend AB to Q on the right of B and to P on the left of A. Now, PQ is the line segment which is greater than AB. 1.A line has countless point and it's symbol is AB. 2.Through a point countless line can be drawn. 3.A line cannot be measured. 4.A line has no thickness. Ray: Light come from the sun is an example of ray A ray is a line having only one end point. It's starting point is called it's initial point. It extends only in one direction. It is denoted by an arrow. In the figure shown above OA is a ray. ‘O’ is it's initial point and ‘A’ denotes it's direction. PLANEFIGURES SQUAREP 1.PQRS is a square. 2.A square has 4 vertices. 3.A square has 4 side. 4.All the sides of a square are equal in length. TRIANGLE 1.ABC is a triangle. 2.A triangle has 3 vertices. 3.A triangle has 3 sides. 4.A triangle may have all it's 3 sides equal(equilateral triangle) or two sides equal (isosceles triangle) or all sides of different lengths(scalene triangle). RECTANGLE 1.ABCD is a rectangle. 2.A rectangle has 4 vertices. 3.A rectangle has 4 sides. 4.A rectangle has only the opposite sides equal. CIRCLE 1.A circle is a close round figure. 2.Point O is called the center of circle. The distance of any point on the circle from O is the same. 3.AB is called a diameter of the circle. 4.The distance from the center of a circle to any point on the circle is called the radius of the circle. OA and OB is the radius. It is just half of the diameter. 5.A circle has no sides and no vertices.
