What is translation dilation rotation and reflection?
Here are the most common types: Translation is when we slide a figure in any direction. Reflection is when we flip a figure over a line. Rotation is when we rotate a figure a certain degree around a point. Dilation is when we enlarge or reduce a figure.
What is the translation formula?
To translate the point P(x,y) , a units right and b units up, use P'(x+a,y+b) .
What is the equation for dilation?
The basic formula to find the scale factor of a dilated figure is: Scale factor = Dimension of the new shape ÷ Dimension of the original shape.
What is dilation in math?
Dilation Meaning in Math. Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape.
How do you calculate reflections?
The rule for a reflection in the origin is (x,y)→(−y,−x) .

What is a rotation math?
A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.
What is the formula for reflection y x?
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

How do you calculate dilation?
What are the 6 properties of a dilation?
Properties of Dilation
- Each angle of the figure is the same.
- Midpoints of the sides of the figure remain the same as the midpoint of the dilated shape.
- Parallel and perpendicular lines in the figure remain the same as the parallel and perpendicular lines of the dilated figure.
- The images remain the same.
