Triangle congruence criteria have been part of the geometry curriculum for centuries. For quadrilaterals, on the other hand, these nice tests seem to be lacking. This task addresses this issue for a specific class of quadrilaterals, namely parallelograms.
This task is designed to give students insight into the effects of translations, rotations, and reflections on geometric figures in the context of showing that two figures are congruent.
Students' first experience with transformations is likely to be with specific shapes like triangles, quadrilaterals, circles, and figures with symmetry. Exhibiting a sequence of transformations that shows that two generic line segments of the same length are congruent is a good way for students to begin thinking about transformations in greater generality.
This task has two goals: first to develop student understanding of rigid motions in the context of demonstrating congruence. Secondly, student knowledge of reflections is refined by considering the notion of orientation in part (b).
The goal of this task is to understand similarity as a natural extension of congruence.
The goal of this task is to establish that base angles in an isosceles triangle are congruent.
The goal of this task is to prove congruence of vertical angles made by two intersecting lines and alternate interior angles made by two parallel lines cut by a transverse.

The advantages of using the Canvas learning management system with Microsoft Office 365 apps are highlighted in this module. Each platform has its own features for engaging and connecting with learners. Together, Microsoft Teams' collaboration and communication tools along with Canvas's assignment and evaluation resources give educators a powerful and comprehensive framework for supporting learning in a digital context.
When educators and learners are not in the same room, strategies for communication are essential for continuing the learning process and collaborating with colleagues. In this video you’ll learn how to stay connected, collaborate and coach your students remotely with tools like Pages, Numbers, Keynote, FaceTime, and Messages.
