Angle an angle is a figure formed by two rays with the same initial point.

The figure formed by two rays with the same initial point is know as (a) a ray (b) a line (c) an angle (d) a line segment

The front angle formed at the centre of a circle by an are is half of the angle fromed by the same are at any point on the circle.

ANGLES AT A POINT Angles formed by a number of rays having a common initial point are called angles at a point.

Prove that the front angle formed at the centre of a circle by an arc, is double of the angle formed by the same arc at any point on the circle.

two particles are projected upwards with the same initial velocity v_(0) in two different angles of projection such that their horizontal ranges are the same. The ratio of the heights of their horizontal ranges are the same. The ratio of the heights of their highest point will be
