Unit 4 Transformations Review Day 1

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

How is a vector used to describe a translation?

Back

A vector describes the direction and distance of a translation, represented as where x is the horizontal movement and y is the vertical movement.

Front

What does the vector <-2, 9> indicate?

Back

It indicates a translation 2 units left and 9 units up.

Front

What is reflection in geometry?

Back

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

Front

How many lines of reflection can a shape have?

Back

A shape can have multiple lines of reflection, depending on its symmetry.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a center point and still look the same at certain angles.

Front

Which letters have rotational symmetry?

Back

Letters like 'S', 'O', and 'X' have rotational symmetry.

Front

What is the difference between reflection over the x-axis and y-axis?

Back

Reflection over the x-axis flips the figure vertically, while reflection over the y-axis flips it horizontally.

Front

How do you determine the line of reflection for a shape?

Back

The line of reflection is the perpendicular bisector of the segment connecting corresponding points of the original and reflected shapes.

Front

What is the first step in performing a transformation?

Back

Identify the type of transformation (translation, reflection, rotation) and the specific parameters involved.
