this is the second important topic in CTET Mathematics paper. I had covered important topics of SHAPES & GEOMETRY. in 8 slides i had covered all important topics and related points and formulae. I wish my effort will help you in your CTET Preparation. I will share more slides regarding CTET Mathematics Topics.

3. 2D & 3D Shapes

4. Formulae
solids (3D)
• Rectangular Room/ Box:- If the dimensions of a room are L,
B and H, then the volume of air inside the room is L×B×H cu
unit.
• Marble Balls:- it is a solid spherical shape. If its radius is r,
then volume is 4/3πr3.
• Cubical Dice:- 3d object, have all sides equal. If its
dimension is a, then the volume is a3.
• Cylindrical Glass:- it is a pattern of hollow cylindrical shape.
Volume of liquid in the glass is πr2h cu unit.
• Conical cape:- birthday cap or magician cap. If its base r,
height h, then the volume is 1/3πr2h cu unit.

5. Geometry
• Point:- a point has neither length nor width. It has neither
area nor volume. Every curve is made up of a set of points.
Centre of a circle is point.
• Line:- collection of points that extends forever without
ends.
• Line Segment:- part of line. It has two end point and of
definite length.
• Intersecting Lines:- two lines having same point called
intersecting lines.
• Parallel Lines:- two lines in a plane which do not intersect
anywhere, called parallel line.

6. • Angles:- an angle is made by two line segment with a
common en point.
• Classification of Angles

7. • Triangle:- A closed figure which has three sides, three
angles and three vertices is called the triangle.
• Types of triangle

8. • Quadrilateral:- A figure which is formed by joining any four
non-collinear point is called quadrilateral. The sum of all
angles of quadrilateral is 360.
• Types of Quadrilateral
