Answer:
the building is aged and unique.
If there are twelve angles created, almost all of them are congruent. All the sides have to equal 180. If there are three parallel lines they must have 2 angles on each side. 3*2=6, there is a total of six with a measure of 48.
Since you have not given any choices to choose from there are a multitude of lines that would qualify as parallel to this line. To find a parallel line, any line that has the same slope as this line that is not the exact same line will be parallel. To find the slope, use the formula y2-y1/x2-x1.
4-7/-3-1
that simplifies to
-3/-4
then simplifying to
3/4
so any line that has a slope of 3/4 that is not the exact same line will be parallel to this line.
Standard form : Ax + By = C
y = 2/3x + 1
-2/3x + y = 1....multiply by -3
2x - 3y = -3 <=== standard form
