Summary of Week of March 3rd.

Last week we learned the properties of a parallelogram, rhombus, square, rectangle and Trapezoids.

For the properties of the square :
-Diagonals are congruent
- Diagonals are Perpendicular
- Diagonals bisect the angles.

For Rhombus :
- Two pair of adjacent sides . 4 equal sides
- Diagonals bisect angles.
- Diagonals are perp.

For Rectangle:
- Diagonals are congruent

For Parallelogram:
-Consecutive angles are supplementary
- Opposite angles are equal
- Diagonals bisect each other

For Trapezoid
- One pair parallel lines
- Same side interior add up to 180

These rules were quiet easy to memorize and we had a test on Thursday on this information.
I thought the hardest one to remember was the Rhombus.
We also did an activity on this... Mrs. D gave us a shape and one length or angle and we had to find the rest using all these rules.
We didn't really learn a lot this week. except those properties.
I really like this topic that we are learning in math right now.

I also found some really good sites on helping you with these problems.
