And when we do a rotation the angle of rotation is always from our preimage point to our center of rotation to the planet image point so that’s the angle we want to create to be 180 degrees.
How do you find the center of rotation with a compass?
This is how you do it firstly connect any two corresponding vertices at a and a dash. And find the perpendicular bisector of that line or between those two points.
How do you rotate 90 degrees clockwise?
Step 2 is the same you’re gonna flip X and y so we’re going to flip each of these x and y values for the next step. The first one is going to become negative 6 negative 4 because we’re just flipping.

How do you calculate rotation?
The angle of rotation between the two points or vertices is the number of central angles times the measure of a single central angle: angle of rotation =m×α = m × α .
What is the formula for rotations?
Rotation Formula
| Type of Rotation | A point on the Image | A point on the Image after Rotation |
|---|---|---|
| Rotation of 90° (Clockwise) | (x, y) | (y, -x) |
| Rotation of 90° (Counter Clockwise) | (x, y) | (-y, x) |
| Rotation of 180° (Both Clockwise and Counterclockwise) | (x, y) | (-x, -y) |
| Rotation of 270° (Clockwise) | (x, y) | (-y, x) |
How do you determine direction?
East and west are at right angles to north and south. East is in the clockwise direction of rotation from north. West is directly opposite east. The sun’s position in the sky can be used to determine east and west if the general time of day is known.
Which way is north on a compass?
To find north, pick up the compass and hold it level with the dial on top. The red end of the magnetic needle will point north. Ignore all the other markings on the compass except the direction that the red half of the needle points to.

Rotation describes the circular motion of an object around its center. There are different ways things can rotate. A very familiar kind of rotation is when a spherical, three-dimensional object turns around an invisible line inside its center. This center is called an axis.
How do you know which direction is north?
Use sunrise and sunset for approximate directions.
Face the sunrise and you are facing east; north will be on your left and south will be on your right. Face the sunset and you are facing west; north will be on your right and south will be on your left.
How do you find your position with a compass?
Hold the compass horizontally in front of you with the direction of travel arrow pointing away from you. Use this arrow to guide you to your destination.
