6.1 Classifying Quadrilaterals Pardekooper

You will find the length of the sides of a parallelogram.

Lets start off with some definitions. Parallelogram - opposites are parallel Rhombus - parallelogram with 4 congruent sides. Rectangle - parallelogram with 4 right angles.

Lets start off with some definitions. Square - parallelogram with 4 congruent sides and 4 right angles. Kite - quadrilateral with 2 pairs of adjacent congruent sides and no opposite side congruent. Pardekooper

Lets start off with some definitions. Trapezoid - quadrilateral with exactly one pair of parallel sides Isosceles Trapezoid - quadrilateral with exactly one pair of parallel sides and non-parallel sides congruent Pardekooper

Lets look at an overview Kite Pardekooper

Don’t forget the following: Slope: y 2 -y 1 x 2 -x 1 Distance:

m = (y 2 - y 1 ) (x 2 - x 1 ) m = (-3-1) (5-2) m = -4 3 Find the slope given the points {(2,1), (5,-3)} Pardekooper

Find the slope given the points {(3,5), (-1,4)} m = (y 2 - y 1 ) (x 2 - x 1 ) m = (4-5) (-1-3) m = = 1 4 Pardekooper

Two lines are parallel if and only if they have the same slope. example: Pardekooper Two lines are perpendicular if and only if their slopes are opposite inverses. Pardekooper

Pardekooper Find the distance between two points. (6,6) and (19,6) 13 Pardekooper

Classify the following: A(3,5), B(7,6),C(6,2), D(2,1) Pardekooper Now lets work a problem Graph the points. A B C D Connect the dots In the order They are Written. Now find the slopes. 1 / 4 1 / 4 AB || DC 4 / 1 4 / 1 DA || CB Opposite sides are parallel But not perpendicular so no right angles So that makes it either A parallelogram or A rhombus Find the length of the sides.

Classify the following: A(3,5), B(7,6),C(6,2), D(2,1) Pardekooper Now lets work a problem AB =  (7-3) 2 +(6-5) 2 =  17 BC =  (6-7) 2 +(2-6) 2 =  17 CD =  (2-6) 2 +(1-2) 2 =  17 DA =  (3-2) 2 +(5-1) 2 =  17 Rhombus

Here comes the assignment.
