Describe at least two similarities between constructing a perpendicular line through a point on a line and constructing a perpendicular through a point off a line.

Construct a line through P perpendicular to given line. Place your compass point on P and swing an arc of any size that crosses the line twice. Place the compass point on one of the two locations where the arc crossed the line and make a small arc below the line (on the side where P is not located). For off the line Perpendicular to a line from an external point It works by creating a line segment on the given line, then bisecting it. The bisector will be a right angles to the given line.

answer: true

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
