Great resource Thank You
So useful<br /> Thank you. A nice range of problems on the worksheet.
This is a terrific resource - I love that the practice worksheet asks students to give reasons for why they found the angle measures. Otherwise, my students just rush through this sort of problem without giving the postulates much thought. Thanks so much!
A good lesson with some nice practice activities.
