Answer 1

ANSWER

From the figure , we can see that  

(1) Interior  

Explanation : Centre O lies in interior of the circle.  

(2) Exterior  

Explanation : Let a point R be such that OR>OP(radius), then R lies in exterior of the circle.  

(3) Diameter.

Explanation : AB , the diameter is the longest chord of the circle  

(4) Semi- circle  

Explanation : We can see, the arc AB with its' end points being the ends of diameter is the semicircle.  

(5) Chord  

Explanation : segment of a circle is the region between an arc and chord

(6) Three  

Explanation : three parts are interior, exterior and circumference.
