'''Procedure''':
# In Circle with centre 'A', BD is a chord, 'p' is major arc and 'd' is minor arc which is represented in red and blue colour respectively.
# What do you mean by the minor segment and major segment of a circle?
# Identify minor segment and major segment.
# Identify and measure the Angles in major segment
# If you change the radius of the circle,Did you observe any changes in the angle measurement? (or) Is the measurement of angle dependant on the circle radius?
# Find that all angles in the same segment are equal
Application:
# What is the type of angle subtended by it in the minor segment?
# What is the type of angle subtended by it in the major segment?
# What is type of angle subtended by it in the semi circle?

If a segment subtended an angle 80° at circumference, then what will be the measure of angles subtended by same segment of the circle circumference at the point P and Q?
