How do you measure the distance between a point and a line?

OpenStudy (anonymous):

Take the slope of the line and find the perpendicular slope: the negative reciprocal. Then plug in the point off of the line into the equation and solve for the x-intercept and set up a system of equations. Find the point of intersection and that will be the point you use the distance formula on. Questions?

OpenStudy (anonymous):

THis is because the perpendicular distance is the height which is actually the shortest distance to the line. The true distance.

thanks

OpenStudy (anonymous):

You're welcome :)

Do you know this one Each perpendicular contains a chord. Compare the lengths of the chords.

Is this related to the last question or is it a completely new question?

OpenStudy (anonymous):

related to the last question

I had to draw a circle on tracing paper and draw two radii.

OpenStudy (anonymous):

Can you draw it possibly?

OpenStudy (anonymous):

and make two congruent segments on each radios

OpenStudy (anonymous):

Possible draw it using the draw feature? It's kinda hard to imagine.
