What is the grade level and CCSS mathematics domain and standard/s for this lesson? Thank you for posting it!


I use this with my 8th graders.

CCSS.Math.Content.HSG-GPE.B.5 Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).

It's a starting step towards being able to do this.
