Transformations, congruence, and similarity
Learn about geometric transformations and how they're used to understand the meaning of "similar" and "congruent".
This course contains 8 segments:
Line of symmetry
A line of symmetry for a two-dimensional figure is a line across the figure such that the figure can be folded along the line into matching parts. In this tutorial, we'll identify line-symmetric figures and draw lines of symmetry.
Transformations intro
Identify transformations, including translations, rotations, reflections, and dilations.
Translations
Learn about transformations and how to perform them.
Rotations
Learn about rotations and how to perform them.
Reflections
Learn about reflections and how to perform them.
Properties & definitions of transformations
Let's continue our deep voyage through the world of transformations! Use your knowledge about the precise descriptions of the rigid transformations and their properties in various situations.
Dilations
In addition to the three rigid transformation, there are the dilations, which expand or shrink figures while keeping the same proportions. These are extremely important in the subject of Similarity! Gain experience by performing dilation, learn how to find the dilation that maps a given figure to another, and learn how to manually draw the image of a dilation.
Congruence and similarity
Learn about congruence and similarity, specifically as they relate to transformations. Learn to dilate shapes.
