Videos to help with stamp project:
signing into geogebra, making a file, exporting to tinkercad, making STL: link
accessing saved work from geogebra; link
calculating slope to show parallel and perpendicular in google docs: link
Warm up was to determine if two linear equations were parallel ,perpendicular, or neither. Learned how to graph parallel and perpendicular lines on the plane and how to write the equation of a perpendicular bisector using Point-Slope Form. Then worked on the stamp project some more.
Notes from board
Homework
p. 97-98: #2-14 (even) and 15
finish stamp project (see Monday above for help videos)
Resources

determine if equations graph parallel, perpendicular lines or neither: link
graph a line perpendicular to given line, through given point: link
finding equation of a line through given point parallel to given line: link
Warm up was to write the equation of a line perpendicular to given line, through a given point. Wen over homework, did a reflection on the stamp project, then began unit of proof and logic and proved that vertical angles are always congruent. Then did the angle copy and angle bisection constructions.
