Question 10 B
Julie is asked to prove that
AB – DC and
AD = BC on the parallelogram shown above. Her proof is shown below.
1
Step Statement
AB || DC and AD || BC by definition of a parallelogram
2 DB is a transversal therefore Zb - Zd and Za Zc
3
DB DB
4
A DAB AA BCD
5
AB-DC and AD BC
Which reason supports the statement she made in step 5 of her proof?

since both sides equal, there are infinitely many olutions.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
