## Presentation Transcript

1. Class: IV Sub: Maths TOPIC: CARTS AND WHEELS Prepared by :Mr A.K. Pathak

2. We can find many such round things around us

3. We can trace a circle with the help of these things

4. Big circle Small circle

5. Properties of Circle O Diameter Radius Chord

6. Centre • Centre: Each point of a circle is at equal distance from a fixed point. The fixed point is called the centre of the circle. • Centre is in the interior part of the circle but centre is not a part of a circle.

7. Radius • The distance from the centre to any point on the circle is called the radius of the circle.

8. Diameter • A line segment passing through the centre and whose end points are on the circle is called the diameter of the circle.

9. Chord • A line segment whose end points are on circle is called a chord. • Diameter is a longest chord of the circle.

10. Circumference • The length of a circle is called a circumference.

11. Assessment Fill in the blanks 1. -------- is not a part of a circle. 2. Centre lies in the -------- part of a circle. 3. Diameter of a circle is ----------- of the radius. 4 . ------------ of the circle is half of its diameter.
