Consider the original parallelogram and the enlargement.
15 mm
5 mm
10 mm
figures not drawn to scale.
what is the length of side b in the enlarged parallelogram?
15 mm
30 mm
40 mm
50 mm

30mm

Step-by-step explanation:

Small Parallelogram= 5×10

Big Parallelogram= 15×?

15÷5=3

?÷10=3

?=30

30÷10=3

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
