Equation of a Perpendicular Bisector Flashcards
1
Q
What is a perpendicular bisector?
A
A line that passes through the midpoint of two points creating a right angle
2
Q
What is Step 1?
A
Find out the midpoint
3
Q
What is Step 2?
A
Find the gradient
4
Q
What is Step 3?
A
Invert the gradient and change the sign (as is perpendicular, it is the opposite gradient)
5
Q
What is Step 4?
A
Substitute the midpoint and inverted gradient into equation y-b=m(x-a)
6
Q
Both gradients (inverted and original) should multiply to make what?
A
-1
