1. Definition and Types of Transformations: Geometry Unit 1 Transformations Answer Key

Geometric transformations are mathematical operations that map one geometric figure onto another. They are used to study the properties of figures and to solve geometric problems.

There are four main types of transformations: translations, rotations, reflections, and dilations.

Translations

• A translation moves a figure from one point to another without changing its size or shape.
• The translation vector is the vector that describes the distance and direction of the movement.

Rotations

• A rotation turns a figure around a fixed point by a given angle.
• The center of rotation is the fixed point.
• The angle of rotation is the measure of the turn.

Reflections, Geometry unit 1 transformations answer key

• A reflection flips a figure over a line, called the line of reflection.
• The line of reflection is the perpendicular bisector of the segment connecting any two points on the figure.

Dilations

• A dilation increases or decreases the size of a figure by a given factor.
• The center of dilation is the fixed point.
• The scale factor is the factor by which the figure is enlarged or reduced.

Top FAQs

What are the different types of transformations?

How do I perform a translation?

To perform a translation, move the figure a specified distance in a specified direction.

What is the effect of a rotation on the coordinates of a figure?

A rotation changes the coordinates of a figure by rotating them around a fixed point.
