Question

→ Draw the symmetry of 15 geometrical figures.
→ Draw and find out the faces, edges and vertex of the following 3 shapes and give two examples of each- a) cubes b) cuboids c) cylinder d) Sphere e) cone f) prism (triangular/square)​​

Answer 1

Answer:

Check internet by asking each question at a time, and u can construction symmetry very easily.

Try to do it yourself

Answer 2

Step-by-step explanation:

1.Symmetry:-

Any line along which we can fold a figure so that the two parts of it coincide exactly is called a line of symmetry or axis of symmetry.

• It can be horizontal or vertical or diagonal.

• The dotted line represents a line of symmetry.

• An equilateral triangle has 3 lines of symmetry.

• A rectangle has two lines of symmetry.

• A circle has infinitely number of lines of symmetry.

See the above attachment

2)a)Cube:-

• Faces = 6
• Edges = 12
• Vertices= 8

b)Cuboid:-

• Faces = 6
• Edges = 12
• Vertices= 8

c)Cylinder:-

Faces = 3

Edges = 2

Vertices= 0

d)Cone:-

Faces = 2

Edges = 1

Vertices= 1

e)Sphere:-

Faces = 1

Edges = 1

Vertices= 0

f) Triangular Prism:-

Faces = 5

Edges = 9

Vertices= 6

g)Square Prism:-

Faces = 6

Edges = 12

Vertices= 8

• There is a relationship among the faces ,edges and vertices of a polyhedron figure is V+F = E+2 .This formula is known as Euler's Formula.
