An ellipse slides between two straight lines at right angles to each other. The focus of its centre is part of

Angle between pair of straight line

An ellipse slides between two perpendicular straight lines.Then identify the locus of its center.

y-1=m_(1)(x-3) and y-3=m_(2)(x-1) are two family of straight lines,at right angled to each other The locus of their point of intersection is

Two vector vecA and vecB are at right angles to each other, when

An ellipse slides between two perpendicular lines the locus of its centre , is

If a bar of givenlength moves with its extremities on two fixed straight lines at right angles,then the locus of any point on bar marked on the bar describes a/an :

Two vectors vec(A)and vec(B) are at right angles to each other then

Angle between y axis and a straight line

A bar of given length moves with its extremities on two fixed straight lines at right angles.Show that any point on the bar describes an ellipse.
