If A, B and C are three points on a line, and B lies between A and C (see figure), then prove that AB + BC = AC.

If A, B and C are three points on a line and B is between A and C then prove that AC - BC = AB.

If A.B and C are three points on a line,and B lies between A and C then prove that AB-BC=AC

A , B and C are three points such that AB = AC + CB , then A , B and C are "_______" .

Draw any line segment,say AB .Take any point C lying in between A and B .Measure the lengths of AB,BC and AC.IsABAB=AC+CB [Note : If A,B,C are any three points on a line such that AC+CB=AB, then we can be sure that C lies between A and B.

In figure A, B and C are points on OP, OQ and OR respectively such that AB || PQ and AC || PR. Show that BC || QR.

A, B and C are three points on a circle. Prove that the perpendicular bisectors of AB, BC and CA are concurrent.

In the given figure A, B and C are points on OP, OQ and OR respectively such that AB||PQ and BC||QR. Show that AC||PR.
