1. what is the solution to the system?
2. which method would be most efficient to solve the system?
√((7 - (-3))^2 + (-6 - (-9))^2) = √109 = 10.44
length of ab = length of a′b′
the figure is only rotated not translated, so the length of the sides remains the same
ab = a'b'
bc = b'c'
cd = c'd'
for this case, we have that by definition:
the supplementary angles are those that in pair add up to 180 degrees.
on the other hand, a linear pair is a pair of adjacent angles formed when two lines intersect each other.
by definition, the two angles of a linear pair are always supplementary, this means that their measurements add up to 180 degrees.
the two angles of a linear pair are always supplementary
2. which method...
