We went over the homework last night, emphasizing the 4 proofs involving parallelograms. We then went through today's lesson that focused on more theorems involving parallel lines. We talked more about equidistance between parallel lines and how this can be used to solve various types of problems. We also introduced the concept of a midsegment in a triangle and how the properties of midsegments can be used in working with parallel lines. The students then got started on their assignment.
Assignment: section 5-3; page 180-181; WE #1-19 all
