Geometry- Wednesday, February 24

Classwork: Went over the review for tomorrow's test. Students need to make sure they are fully stating the criterion they are using for showing that a quadrilateral is a rectangle, square, rhombus or parallelogram. Shortcuts are not recommended and very few of these criterion have "names", thus it is important to say the entire criterion. For example "consecutive angles theorem" does not exist! However, "If parallelogram then consecutive angles are supplementary" says everything we need to know, but it isn't the same as saying that one angle is 100 and another is 80 (This has been a common shortcut, which is not accurate. The angles can be any two numbers that add to 180, so a better way would be to say one angle = x and the other = 180-x).

Homework: Study for tomorrow's test! I have posted the key in the math folder.
