In Grade 8, students study rigid motions using physical models or software, with an emphasis on geometric intuition, whereas high school geometry weighs precise definitions and geometric intuition equally.
Attend to precision.
What is the minimum amount of information you need to know about two triangles in order to determine if they are congruent? Why is that the minimum?
How can transformations be used to prove that two triangles are congruent?
In high school, students will compare graphs of functions and other curves to make congruence and similarity arguments based on rigid motions.
