Parallel and perpendicular lines help please! 10 questions fan + medal 1. Construct the line perpendicular to TU at point V. 2. Construct the line that is perpendicular to the given line through the given point. 3. Plans for a stadium are drawn on a coordinate grid. One wall lies on the line y=2x+3. A perpendicular wall passes through the point (4,-7) write the equation of the line that contains the new wall. 4. What is the graph of 5x -3y = 15. 5. Which lines are parallel if m<4 = m<5? justify your answer. 6. Write the equation for horizontal line that contains point G(-8,8).
possible answers on #2 I'd like to understand
1 is not correct
the question on #5 If you guys don't have time to explain it's fine if you already know the answers. I just want to understand since it's kind of a course without much help from teachers.
Should be B
Well it's actually hard for me to explain. Maybe try looking on YouTube or khan academy about constructing perpendicular lines
@nikato what about #2, #5 and Write and equation in point-slope form of the line through point J(4,1) with slope -4. I watched a few videos but it's confusing
https://www.khanacademy.org/math/geometry/geometric-constructions I thouroughly recommend watching these videos. They will really help.
2. Is hard to explain. Try watching ^that video. And for 5. Hint. Which two lines if parallel would make those two angles congruent by alternate interior angles
2. Hint: What do you know about isosceles triangles?
@nikato R an S? and @FibonacciChick666 Nothing really but my guess on the answers is A or B
One of them is correct
And yes. 5. Is right.r and s would be parallel
@FibonacciChick666 Well i said A because it looks right but i'm not sure
And look at if you construct the altitude of an isoceles
if you construct two isoceles in this form, can you figure out why?|dw:1394937521724:dw|
because they are perpendicular?
No this would be the first step of the construction
|dw:1394937708562:dw| The perpendictlar will pass through pt A, but why? Also did you watch the video?
I tried looking for the video on the link i saw a few but i didn't see the one you were referring to. And on this Write and equation in point-slope form of the line through point J(4,1) with slope -4. would this be right. y-1=-4(x-4)
yup that is correct
and let me find it
That will show you exactly how
So it's b?
@FibonacciChick666 what about #1 a. an angle congruent to a given angle. (my choice) b. the bisector of an angle. c. the bisector of a line segment d. a perpendicular to a given line from a point on the line. #2 a. a perpendicular to a given line from a point on the line b. a line segment congruent to a given line segment c. the perpendicular to a given line from a point not on the line (my choice) d. the perpendicular bisector of a line segment
sorry but i'm going to bed, and I don't like any of the provided answers
@nikato
Sorry. I'm not quite sure but 2. And I think that 1 is right
