Rotational Symmetry.
There are 360 degrees at the centre of any figure.
A circle
There are 900 degrees in a seven sided figure!!
360 degrees are formed because angles around a point add up to 360 degrees.
Rotating a figure 270 degrees is like rotating the figure to the left 90 degrees. I am not sure what formula or rule you use. *Joe Jonas Rocks*
There are 360 degrees at the centre of any figure.
If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotation symmetry. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation. This figure has rotation symmetry of 72°, and the center of rotation is the center of the figure:
If it's an *equilateral* triangle, a triangle. Check out quadrilaterals (squares, rectangles), then *equilateral* pentagons, hexagons, etc. Generally, an equilateral polygon needs only rotate (360/number of sides) degrees to coincide.
A circle
There are 540 degrees in a five sided figure.
There are 900 degrees in a seven sided figure!!
360 degrees are formed because angles around a point add up to 360 degrees.
His the center figure of Civilization, of Philosophy, of History, of true theology Christianity.

When you rotate it around a point found in the middle of the figure 180 degrees. For example, H does have rotational symmetry however, E doesn't
It has rotational symmetry of order 2 or more.
The property is Reflection Symmetry, Line Symmetry or Mirror Symmetry
