How many times does a rectangle coincide with itself within one full 360-degree turn? explain.

2 times does a rectangle coincide with itself within one full 360-degree turn.

Step-by-step explanation:

To find : How many times does a rectangle coincide with itself within one full 360-degree turn?

Solution :

A rectangle is the shape with rotation symmetry.

A rectangle can be rotated about its center and it will look exactly the same and be in the same location.

The only difference is the location of the named points.

Refer the attached figure.

So, In one full 360-degree turn

Th rectangle rotates,

Therefore, 2 times does a rectangle coincide with itself within one full 360-degree turn.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
