which Quadrilateral is it ?!
By: Brittani and Deziure
First we had to plot the points
Then find the slope of each side of the shape
From points A,D
are the sides parallel or perpendicular ?
They are parallel because C,D and A,B slope = -1 and A,D and B,C = 1
Distance between B,C
find the area of the shape
To find the area I multiplied the b*h
Find the midpoints of the each side of the rectangle
Distance between E,F
we found that our new shape was a rhombus , because the both pairs of opposite sides are parallel and that all 4 sides of the shape are congruent.
Perimeter of the new shape
The perimeter of the new shape is 10 , we found the perimeter by adding all the lengths of sides together
