is that the centre?

#

a

yes

B is Circumferential angle and A is Central angle

#

yeah i know that a = 2b but is there a way to prove it?

rigid rain yeah i know that a = 2b but is there a way to prove it?

yeah mathematics definitely has proof

#

name centre as O

#

and circumference point as B

#

nvm I will send ss

o okay

so here angle pod is 180-2a-2b
and angle poc is 180 -2a cause they are isoceles triangles
hence angle doc(angle at circumference is 2b

#

or just do some angle chasing if you don't udnerstand

#

rigid rain ohh i understand

good

#

change it to solved?

#

.solved

#

why does this dosen't work when I do it sad

rigid rain Mar 25, 2023, 1:56 PM

#

.solved

Post marked as solved by @rigid rain.

Use .unsolved if this was a mistake.

rigid rain .solved

can you tell me why can't I do it?

#

what role do I need for it?

rigid rain Mar 25, 2023, 1:57 PM

#

i think its just the poster of the question that can do it

empty otter Mar 25, 2023, 1:57 PM
