Working in pairs, geometry students will construct a dilation and consider the properties associated with the similar figures that are created to verify the properties of dilation. This activity can be done using dot or graph paper and rulers, compasses, and protractors, geoboards, or dynamic geometry software.

Graphic Art Contest
Creativity is endless when your mathematicians take a simple image and use transformations to create their own poster inspired by geometry. While certain rotations and reflections are required, learners will be able to create ten new images by flipping, moving, spinning, and zooming their original using Word.

Here is a lesson plan that starts out with learners creating congruent figures by drawing the exact same polygon as their partner. From here, they have a discussion about why what they drew is an exact copy, followed by other activities that look at different shapes, some with transformations, to determine their congruence.

Similarity and Dilations - Discover Properties of Similar Figures
Learners investigate properties of similar figures. In this properties of similar figures lesson plan, pupils construct similar figures using Cabri Jr. They dilate their figure to create a similar one, and discuss the relationships between the angle measures and side lengths of the two similar figures.

Verifying Triangles are Congruent
Here the focus is on triangle congruence. Through an activity that requires investigation, questioning, and working together, geometers learn to identify corresponding parts of triangles to determine if the triangles are congruent. Triangles are transformed through reflection, rotation, and translation.

Introduction To Transformations Lesson
Students investigate the concept of transformations and how they are used in various types of problems and define the terms of rotation, reflection, translation, and dilation. They practice using the GSP technology to apply practices to display the images in two or three dimensional space.

Dilations and Similarity
In this dilations and similarity worksheet, pupils solve 10 different problems that include various dilations. First, they determine the scale factor of dilations found in the illustrated graphs. Then, everyone determines the coordinates of the image of a point under a dilation with the center at the origin of scale factor.

Dilations in the Plane
In this geometry lesson, students collect and analyze data as they investigate relationships between the pre-image and the image of a triangle. They investigate angle measures, side lengths, and the dilation factor. The dynamic nature of Cabri Jr.

Exploring Quadratic Data Using Translation and Dilation
Mathematicians analyze the vertex form of a parabola and find an approximate fit of a model. They explain the quadratic parabola function and its properties by developing quadratic models. They use translation and dilation to change the general parabola.

Transformations With Lists
Students explore the concept of transformations. In this transformations lesson, students enter data into lists and make a scatter plot of points. Students use lists to transform the data points by shifting the points, left and right, or up and down.

Discovering Math: Exploring Geometry
Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade with classmates, who calculate surface area and volume of some of the structures.
