Algebra 2H pds 1,2
Make sure you review all of the types of factoring for tomorrow's quiz. This includes problems from all of the previous hw assignments on factoring as well as the review sheet problems. You must memorize the formulas for the sum and difference of cubes.
HW Do the puzzle worksheet -this will help you review for finding GCFs and trinomial factoring as well as difference of squares.

EC question...Did you enjoy the problems on factoring? Why or why not?

Geometry H pds 3,5,6
Today, we used the compass and straightedge to construct the perpendicular bisectors and angle bisectors of a triangle. These are examples of concurrent lines (they meet at one point.)
No hw tonight-just bring your compass and straightedge (and today's worksheet) tomorrow as well.

EC problem...Draw an isosceles triangle ABC. (you may construct one with your compass and straightedge). Construct the perpendicular bisectors of each side. Label the point of intersection O. Draw the circumscribed circle with radius OA.
