Question

Refer to the adjoining figure and answer the following questions:
1) Name two chords with common end point A in the in the exterior concentric circle.
_________________________________________________

2) What are the three radii of the interior concentric circle?
________________________________________________

3) What is the diameter of the interior concentric circle?
________________________________________________

4) Name two triangles in the exterior concentric circle whose
vertices lie on the circle. _________________________________________________

Answer 1

Answer:

radius r. O r. The circumference of a circle is the length around the circle. A central angle of ...A circle divides a plane into three parts : interior , exterior and boundary. A boundary together withA chord AB of a circle divides the circle into two segments. If AB is a diameter, the two congruent segments are called semicircles − the word 'semicircle'

Step-by-step explanation:

Solution 1:

(a) O is the centre.

(b) Three radii: OA, OB and OC

(c) A diameter: AC

(d) A chord: ED

(e) Interior points: O, P

(f) Exterior point: Q

(g) A sector: OAB

(h) A segment: ED
