Plane Geometry: Finding the missing angles

[@profrobbob]

Awesome! Very well explained🤓 I like the translations you are adding.

[@rosesarpomaa7624]

Well done sir ☺️
I never understood the circle theorem when I was at school but this your explanation have made me understood
God richly bless you 🙏🙏

[@dezzykitchen1998]

Thank you

[@DotRabbit]

I did it like this, I drew a line parallel and wrote the other angles i got as z and y respectively. Through this i got x+y = 123 eq 1 and x+z = 105 eq2 .And from the straight line line properties i got x+y+z = 180 . Then, i added eq 1 and 2. I got x+y+z+x = 228
Substitute x+y+z= 180 you get x+180=228 you get x = 228-180 = 48.
For the second one we can draw a radius OA. You get OA = OB= OC .
Then, those two are isosceles triangle formed. Angle OBA = OAB = 30. Then Angle OAC = 20. Since isosceles triangle property states two adjacent angles are equal when their corresponding sides are equal. OAC= OCA = 20.

[@IdaDanso]

Thank you sir for the wonderful explanation ☺️

[@seriousgamer05pami79]

This has helped me understand angles and using parallel line to my advantage and sir can I say you have a very good eye for finding different ways to solve problems 0:53 and 1:34

[@mustaphatijjanimuhammad4672]

How I hope I get maths teacher during my days at secondary school like you all will be easy for me. Thanks for your anticipated effort.

You make me to understand this other type of geometry thank you very much

[@tambuwalmathsclass]

🙏🙏

[@我是我-k2r]

Case 1: 105+123-180= 48. In 2nd case. OA=OB (Radius) so angle BAO = 30 degree AOC=20 degree. OA = OC so angle ACO=20 degree.

Thank you so much...I needed someone to make me understand this two topics and you did it in just two diagrams

[@tambuwalmathsclass]

🙏🙏🙏👍👍👍

[@zakariyeidiriz7514]

Question two sir
Just you can do very shortcut way.
First find angle of centre is 100 right
Then 360_100
Equal 260
So you can found y by quataleral
By adding of 50+30+260+y= 360
Then like terms y= 20😂

Whenever a chord subtends an angle to centre it forms an isosceles triangle
