Even with a snow day, we are still headed towards a unit test before spring break. Plan on having a unit test Thurs-Fri, March 14-15.
Today we finished up our conjectures for the unit:
C-46 - Diagonals of a rhombus bisect the angles of the rhombus.
C-47 - Diagonals of a rhombus are perpendicular bisectors of each other.
C-48 - Diagonals of a rectangle are congruent.
C-49 - Diagonals of a square are congruent perpendicular bisectors of each other, and also angle bisectors.
We had a warm-up in class to practice naming polygons, define regular, and find sum of angles and one angle in regular. We also practiced finding slope of the diagonals of a quadrilateral and using that to determine the type of quadrilateral. There was also a worksheet over kites and trapezoids for which we did 5 problems (attached below... we did 2-4 on front, 13 and 31 on the back).
We went over homework #16 (after taking a 4 pt grade).
Then we looked at fill in the blank proofs of two of the new properties listed above. We will do three of these as a warm-up next time we meet.
We took a quiz today over 5.1-3 for 31 pts.
The rest of the unit will be: practicing proofs of our conjectures, using slope, distance, and midpoint formulas to then determine (prove) the type of quadrilateral for the vertices given, AND "working backwards": I give you properties, you tell me what type of quadrilateral it MUST be or COULD be.
EXAMPLE: I'm a quadrilateral and my diagonals bisect each other.
I MUST be a parallelogram (parallelogram properties). I COULD also be a rectangle, rhombus or square since they are all parallelograms.
IF YOU MISSED THE QUIZ, PLEASE COME DURING A&E ON THURSDAY TO MAKE IT UP!!!
