Rigid Transformations

The term translate means to move for example translate to the right 3 times meant you move to the right 3 spaces. image image image

 

 

 

The term rotate is when you either go clockwise or counterclockwise at a certain point. For example when you rotate at the origin 90 degrees clockwise then at the origin (0,0) you rotate clockwise right.

 

 

 

The term reflect means you mirror it across a certain point on the x axis or the y axis.

 

 

 

 

 

Dilations

Multiplying the coordinates on  a shape can dilate the shape very much. For example of you multiply the coordinates of a shape twice then the whole shape will have twice as much area than it did before. The angles of the shape wont change because its the same angles just in a diffrent position. The results do depend on the multiplier because thats how much the shape is going to dilate for.

 

Finding Similar Shapes

The way you find out if two shapes are similar is that they both have to have the same length and they have to have the same angles as each other. They both dont need to have the same shape though they need the length and angles and theyre the same shape.

 

Finding Missing Sides of Similar Shapes

To find the missing side of a similar shape you have to first identify the sides of the shape that you already have. You have to first solve those shapes. When you solve those shapes then you have to find and match up the angles and lengths to help you find the missing ones.
