What is true about the median.
Cuts the side of a triangle into 2 equal parts.
It is always inside the triangle.
It passes through the midpoint of the side of the triangle and the opposite vertex.
All of the above
If you found the midpoint of line segment AB, what should you do next to find the equation of the perpendicular bisector?
Use the midpoint and one of the points from AB to write the equation
Use the midpoint and slope perpendicular to AB to write the equation
Use the distance and midpoint to find the equation
Use the midpoint and slope of AB to write the equation
What is the equation of the line that passes through the points
(6, 5) and (4, -3)?
y= 4x- 29
y= 4x - 19
y= 4x + 19
y=-4x -19
What is the equation of a line that is perpendicular to the line y = 3x + 2 and goes through the point (3, -4)?
y = 3x - 2
y = -1/3x - 5
y = 3x - 4
y = -1/3x - 3
Points A(1,3) & B(-3,5) are the endpoints of a chord on a circle with centre not at the origin. What is the equation of the perpendicular bisector of chord AB?
y = 2x + 4
y = 2x + 6
y = -2x + 6
y = 2x - 6
