Question

I Observe the given circle
with centre O and identify the
following
a) 2 radii
b) A chord
c) Is OR = OB. Give reason.
d) Is AB = 2 x OS ? Give reason.​

Answer 1

1. OR & OS
2. DE
3. Yes, because they both are radii of same circle
4. Yes , because AB is the diameter and OS is a radius , and we know that diameter is always two times the radius

HOPE THIS WILL HELP YOU!

Answer 2

Answer:

a) OA, OB, OR, OS

b) DE

c) Yes

d) Yes

Step-by-step explanation:

a) Radius is a line segment joining the centre of the circle to the circumference. Therefore, OA, OB, OR, OS are the radii of the same circle.

b) A chord joins two ends of a circle and may or may not pass through its centre. Diameter is the longest chord which passes through the centre of the circle.

c) Yes, OR = OB because they are the radii of the same circle.

d) Yes, AB = 2 x OS because a diameter is always twice the radius of the circle while a radius is half the diameter.
