Question

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

Answer 1

Twice

Explanation:

A rectangle will look the same it rotate it 180 degrees and of course when you rotate it a full 360 degrees. 360/180 = 2, two times the rectangle will coincide with it itself.

Answer 2

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

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
`180^\circ` 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,
`(360)/(180)=2`

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