Transformations on the Coordinate Plane
Here is a study guide on transformations that includes reflections, translations, dilations, and rotations. It also has definitions, helpful diagrams, and several examples involving transformations on the coordinate plane. The lesson...
Curated OER
Reflections
Learners explore reflection of polygons on a coordinate plane. They examine the relationships that exist between corresponding points and sides.

Exploring Transformations with Matrices
A page right out of the Holt Geometry book. Use a graphing calculator and graph paper to explore transformations with matrices.
Curated OER
Transformations: Translations
High schoolers perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.
Curated OER
Matrix Transformations
Students perform reflections of polygons. In this algebra activity, students use matrices to calculate the reflection across the x and y axis. They also calculate rotation representing 90 and 180 degrees around the origin of the...
Curated OER
Exploring Transformations: Translations and Reflections
Learners perform translation and reflection. They identify the coordinate points of the new graph and create a formula for the movement. They identify the pre-image the and after image.
Curated OER
Transformations: Reflections
Students perform transformations on their graphs. In this algebra instructional activity, students identify the pre-image and image. They find and identify congruent shapes and isometry.
Curated OER
Transformations and Rotations
Students define and identify transformation and rotation. In this geometry activity, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.
Curated OER
Glide Reflections
Perform reflections and transformations by having your high schoolers create glide reflections from translated shapes. They use the TiNavigator to explore transformations.

What's the Spin?
Learners use the CABRI application for their graphing calculator to rotate, translate, and reflect triangles. They use graphing calculators and follow detailed directions to manipulate triangles in specified ways. There are three...
Curated OER
Reflections in the Plane
Have your class explore the concept of reflections as they use Cabri Jr. to construct a triangle and reflect it over a line. Learners reflect shapes across the coordinate plane and across the lines y = x and y = -x.
Curated OER
Rotations in the Plane
Pupils investigate the properties of a rotation as they use technology (Cabri, Jr.) to observe the relationship between the pre-image and the image formed by the rotation. The lesson provides ample opportunity for learners to conjecture...
Curated OER
Connecting Translations, Reflections, and Rotations
Learners differentiate between translation, reflection and rotation. They explore the 3 types of transformation using Cabri Jr. and build on previous knowledge in this lesson.
Curated OER
Handy Reflections
Learners explore reflections on a coordinate plane in this lesson. They trace their hand on a grid, determine the coordinates of each point, and create a scatter plot of their points. Pupils use this information to investigate aspect...
