it is used to find the distance between twopoints on the coordinate plane

Pythagorean Theorem can be used to findthe distance between two points.

the midpoint of a segment is a point thatdivides the segment into two congruentsegments

to find the midpoint of a line, simply findthe x and y coordinates of the midpoint

to find the x coordinates

to find the y coordinates

the shortest distance is the one drawnperpendicular to the line.

In mathematics , CIRCLE is defined as theset of all points equidistant from a fixedpoint called center

The center C is at (h, k), r is the radius andP(x, y) is a point on the circle.

the distance formula is used to find theequation of the circle

Two lines are parallel if they have the sameslope and different y intercepts

Two lines are perpendicular if their slopesare opposite reciprocals

we can graph linear equations using

linear equations can be written in 3 forms
