Transformations review Hon

Front

What is the slope of two parallel lines?

Back

The slope of two parallel lines is the same.

Front

What happens to the slope of a line when it is translated?

Back

The slope remains unchanged when a line is translated.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but not its shape, represented as (x,y) -> (kx, ky) where k is the scale factor.

Front

If point H(-6, 2) is translated 4 units up and 3 units right, what are the new coordinates?

Back

The new coordinates are (-3, 6).

Front

How do you reverse a translation of 2 units down and 3 units right?

Back

Translate it 3 units left and 2 units up.

Front

What is the measure of an angle after a translation?

Back

The measure of an angle remains the same after a translation.

Front

What is the effect of translating a shape on its orientation?

Back

The orientation of the shape remains unchanged after translation.

Front

What is the transformation represented by (x,y) -> (-x,-y)?

Back

This represents a reflection over the origin.

Front

What does the transformation (x,y) -> (x+5,y-8) represent?

Back

This represents a translation of the figure 5 units right and 8 units down.

Front

What is the result of reflecting a point over the x-axis?

Back

The y-coordinate of the point changes sign.
