Transformations - Flip, Slide, Rotate, and Grow Your Math Skills!
Welcome to our exciting module on transformations in geometry! In this module, we will explore how shapes can move, flip, slide, and change in size, all while maintaining their essential properties. Transformations are not just mathematical concepts; they are all around us in art, architecture, nature, and even video games!
As we dive into this learning module, we'll also deepen our understanding of congruent and similar figures. Congruent figures are exact copies of each other, while similar figures have the same shape but may differ in size. You’ll learn which transformations result in congruent images—like translations, rotations, and reflections—and which ones create similar images, such as dilations.
To make this module engaging and interactive, we will be using the many video lessons below to help you visualize and understand each type of transformation. Each video will introduce a new transformation, complete with demonstrations and practice problems to reinforce your understanding. Get ready to see how transformations can create beautiful patterns, help solve puzzles, and even change the way we look at shapes! So, grab your notebooks, keep an open mind, and let’s dive into the fascinating world of transformations! Your journey into geometry starts now!
Lesson Objective: Students will be able to identify and describe congruent figures and understand the properties of congruence.

Lesson Objective: Students will be able to rotate a given geometric figure 90°, 180°, and 270° about a specified point on the coordinate plane, and accurately describe the position of the resulting image using coordinates.
Essential Question: How does rotating a figure about a point differ from rotating it about the origin on the coordinate plane?
Lesson Objective: Students will be able to identify similar figures, name corresponding angles and sides, and find unknown measures using the properties of similar figures.
Essential Question: How can you use a proportion to determine if two figures are similar?
