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

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

In given figure, name all rays with initial points as A, B and C respectively.

Construct an angle of 60^@ at the initial point of a given ray.

Find out the incorrect statement, if any, in the following An angle is formed when we have (a) two rays with a common end-point (b) two line segments with a common end - point (c ) a ray and a line segment with a common end - point

To construct an angle of 60^(@) at the initial point of a given ray.

What are the initial and final shells for an M_(beta) line in an x-ray spectrum?

Use the figure to name: (a) Five points (b) A line (c) Four rays (d) Five line segments

Write which of the following statement are true and which are false (i) A simple closed figure made up of three or more line segments is called a polygon (ii) Part of a line with two end points is called a line segment (iii) In geometry we take a point a line and plane as undefined terms (iv) Euclid fourth axiom says that everything equals itself (v) The Euclidean geometry is valid only for figure in the plane (vi) A figure formed by two rays with a common initial point is called an angle

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