Draw a straight line AB and take a point P outside AB. Draw a straight line parallel to AB from point P...

To construct a line parallel to a given line and passing through a given point outside the line. Question : Draw a line l, take a point P outside it. Draw a line m || line l passing through point P.

If C is the mid-point of AB and P is any point outside AB, then

If C is the middle point of AB and P is any point outside AB, then

AB is a straight line, C and D are points on the same side of AB such that AC is perpendicular to AB and DB is perpendicular to AB. Let AD and BC meet at E. What is (AE)/(AD) + (DE)/(BC) equal to ?
