What is the definition of the geometrical patterns of "JHAROKHA"?

State ‘T’ for true and ‘F’ for false.

          (a) A quadrilateral is a five sided polygon.

         ( b) All the four sides of a rhombus are equal.

         (c) A trapezium has all angles equal.

         (d)  Half of a revolution is a straight angle.

Which pattern is made in a circle?

Write P for plane figure and S for solid figure in the box. 
   

Identify the figure as triangle and quadrilateral. Give reasons.

Identify whether the following polygon is a triangle or not$?$

Draw some Jharokha patterns on the given wall and shade it in black colour.

Identify whether the following polygon is a triangle.

Identify whether the following polygon is a triangle or not$?$

 Identify the figure given below.

Identify whether the following polygon is a triangle or not?

(i) The opposite sides of a parallelogram are $\underline{P }$and $\underline{Q}$.
(ii) A quadrilateral having only one pair of opposite sides parallel is called a $\underline{R}$.
(iii) A parallelogram having all sides equal is called a $\underline{S }$.

Now colour some bricks red and make your own 'jaali' patterns in the wall drawn below.

How many different 'jaali' patterns can you see in these two photos?
