What are the angles of rotational symmetry?

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.

Example

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 degree of rotational symmetry. A square has rotational symmetry of degree 4.

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.
