Front

What is Reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line (axis), creating a mirror image.

Front

What is Translation in geometry?

Back

Translation is a transformation that moves a figure from one location to another without changing its shape or orientation.

Front

What does it mean to translate a figure 6 units left and 3 units up?

Back

It means to move every point of the figure 6 units to the left on the x-axis and 3 units up on the y-axis.

Front

What is Dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but keeps its shape the same, using a scale factor.

Front

What is Rotation in geometry?

Back

Rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.

Front

What is the effect of a Reflection over the y-axis?

Back

A reflection over the y-axis flips the figure horizontally, changing the sign of the x-coordinates.

Front

What is the effect of a Reflection over the x-axis?

Back

A reflection over the x-axis flips the figure vertically, changing the sign of the y-coordinates.

Front

How do you identify a Translation?

Back

A translation can be identified by the consistent movement of all points in the same direction and distance.

Front

If point K is at (-4, -2) and is translated 3 units to the right and 4 units up, what are the new coordinates?

Back

The new coordinates of point K would be (-1, 2).

Front

What is the difference between Reflection and Rotation?

Back

Reflection creates a mirror image over an axis, while rotation turns a figure around a point.
