excellent introduction to angles with parallel lines
Community Review for GeoGebra
My Take
I like the interactivity of the diagrams where the kids can manipulate the drawings so they can explore what happens to the angles when they move the lines around. I think the tutorials should be the first thing they give you the first time you sign up. I see great potential with the interactive worksheets for the students to use later on in the course. I really like the ability to enter LaTeX for formulas that are beyond a strictly text inputs
