Are We the Same?
Learners define and discuss symmetry, line of symmetry, and congruency. They cut shapes out of construction paper, identify the line of symmetry, and if they are symmetrical and/or congruent.

Translations, Reflections, and Rotations
Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.
Curated OER
Transformations and Translations
In this transformations/translation worksheet, students draw transformations based on shapes and vectors of given translations. A reference web site is given for additional activities.
Curated OER
Similar and Congruent
In this similar/congruent worksheet, students determine whether pairs of shapes are congruent, similar but not congruent, or neither similar or congruent.
