## What happens to a shape when you rotate it?

Rotating shapes means moving them around a fixed point (clockwise or anticlockwise, and by a certain number of degrees). The shape itself stays exactly the same, but its position in the space will change.

## Does a rotation flip a shape?

Conventionally, shapes are rotated counterclockwise on a coordinate plane. You should assume this, unless it is noted in the problem that you need to rotate clockwise. For example, if the problem states, “Rotate the shape 270 degrees around the origin,” you can assume you are rotating the shape counterclockwise.

**What happens when a figure is rotated 180 degrees?**

180 Degree Rotation When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.

### How do you describe the shape of a rotation?

A rotation is a turn of a shape. A rotation is described by the centre of rotation, the angle of rotation, and the direction of the turn. The centre of rotation is the point that a shape rotates around. Each point in the shape must stay an equal distance from the centre of rotation.

### What does it mean to reflect a shape?

Reflecting a shape means to flip the shape over a mirror line. To reflect a shape we move the corners and then join them together at the end. The reflected shape image is the same size and shape as the original object.

**How do you rotate points around the origin?**

The rule for a rotation by 90° about the origin is (x,y)→(−y,x) .

#### How do you rotate an object around a point?

Do one of the following:

- To rotate around a different reference point, select the Rotate tool. Then Alt‑click (Windows) or Option‑click (Mac OS) where you want the reference point to be in the document window.
- To rotate around the center point, choose Object > Transform > Rotate, or double-click the Rotate tool.

#### What is 360 rotation?

A full rotation is 360 degrees “Doing a 360” means spinning around completely once (spinning around twice is a “720”). “I gave the wheel one complete turn looking for holes” “It completed one cycle”, meaning it went around exactly once. “She went full circle on liking carrots”.

**How do you do a 270 degree rotation?**

The rule for a rotation by 270° about the origin is (x,y)→(y,−x) .

## Can you rotate a shape in any direction?

All you have to do is remember some very simple definitions and rules and you can rotate just about any shape about the origin. A rotation in the counterclockwise direction has an angle with a positive measure, while a rotation in the clockwise direction has an angle with a negative measure.

## What’s the best way to rotate a circle?

For example, take the center point of your larger single circle, then take one of the smaller circles and have it’s edge connected to that center point. Now the next small circle, would be pivoted 36 degrees from that first small circle but attached to the same center point.

**How do you rotate an object in Excel?**

In the Rotation box in the task pane, enter the amount that you want to rotate the object (such as 45, 90, -45 or -90) and then press Enter. You can also click the arrows in the Rotation box to rotate the object. The Format Shape task pane appears as follows tor a shape with 45 entered in the Rotation box:

### How do you rotate a triangle on a graph?

Simply place those three points on the graph, connect the dots, and presto! You’ve just rotated your first shape. Ok, let’s try another one. Let’s rotate the original triangle, with the same starting points of (3,-1), (1,0), (2,1) by 270 degrees about the origin this time.
