2
The opposite sides of a parallelogram are __________ and __________

3
The opposite sides of a parallelogram are parallel and congruent: > > > > > >

4
Given the following parallelogram, find x and y: 10 8 x y

5
x = 8 y = 10

6
The opposite angles of a parallelogram are __________.

7
The opposite angles of a parallelogram are congruent. 70 0 110 0

8
The diagonals of a parallelogram __________________________.

9
The diagonals of a parallelogram bisect each other: 12 8 8

10
The diagonals of a rhombus are __________ and ___________.

11
The diagonals of a rhombus are perpendicular and bisect opposite angles: 30 60 30 60

12
The diagonals of a rectangle are __________________.

13
The diagonals of a rectangle are congruent: LN HS LH = NS

14
Name the sides of the following trapezoid: 1 2 3 4

15
1- leg 2- base 3- leg 4- base

16
The __________ of a trapezoid connects the midpoints of the legs

17
The midsegment of a trapezoid connects the midpoints of the legs:

18
Find the length of the midsegment: 10 20

19
Midsegment = ½ (10 + 20) = 15

20
Midpoint Formula: A (x 1, y 1 ) B (x 2, y 2 ) M ( _____, _____ )

21
x 1 + x 2 y 1 + y 2 2 2, Midpoint = average

22
Find LN: L ( x 1, y 1 ) N ( x 2, y 2 )

23
LN = (x 1 – x 2 ) 2 + (y 1 – y 2 ) 2 (Distance Formula)

24
