If two rays intersect will their point of intersection be the vertex of an angle of which the rays are the two sides ?

Point of intersection of tangent at any Two points on the Parabola

Locus of Point of intersection of two normal of parabola which are at right angle to one other

If two equal chords of a circle intersect within the circle,prove that the line joining the point of intersection to the centre makes equal angles with the chords.

If two circles intersect at two distinct points , then the number of common tangents is __________.

Vertex for any two edges that meet at an end- point there is a third edge that also meets them at that end-point.This point of intersection of three edges of a cuboid is called a vertex of the cuboid.

Parallel rays two rays are parallel if the corresponding lines determined by them are parallel.In other words two rays in the same plane are parallel if they do not intersect each other even if extended indefinitely beyond their initial points.

Statements a and b are as given below: a : If two lines intersect, then the vertically opposite angles are equal. b : If a transversal intersects, two other lines, then the sum of two interior angles on the same side of the transversal is 180^(@) . Then
