Mathematics

Explanation:

Angles of rotational symmetry are the angles by which you can turn a figure about its center of symmetry so that the rotated figure is indistinguishable from the original.

<u>Example</u>

A square has angles of rotational symmetry of 90°, 180°, and 270°. Rotating a square around its center by any of these angles gives you back exactly the same square.

__

The number of angles of rotational symmetry (including 0°) is the <em>degree</em> of rotational symmetry. A square has rotational symmetry of degree 4.

For the first digit you are choosing from 2 digits
for the second digit you are choosing from 2 digits
for the third digit you are choosing from 2 digits
2*2*2=8

011
101
000
001
100
010
However......
A number doesn't usually start with a 0 or 0s.
Therefore, if you want 3-digit numbers and not just permutations using 0 and 1, then you must eliminate
011, 000, 001, and 010
Seeing that the first digit can't be 0, you choose from 1, then 2, and then 2 digits again; 1*2*2=4 numbers
You choose which answer best suits your problem.
