[@teciRiver]

I have a question about 39:37 why you couldn't do the same for the opposite angles which would mean that angle k+the unknown angle=90 degrees. meaning that the radius from ''o'' to 34 degrees and the unknown angle is equal to line ''o-k'' so 34+k=90 meaning K=56 and then since there are 2 k's. angle at ''l'' would be equal to=68 degrees
(This was just a thought because i found it easier)
Lastly at - 44:48 - is angle ''s'' not (r+70)
thanks

[@ICOMATHS]

Wow. Thanks alot

[@trinityhamied]

I would recommend watching Kerwin Springer video on introductory to circle theorems, and draw all 8 theorems. Then do the practice exercises here. It will be much simpler. Also for some of the theories just use the alternate segment theory which takes no working you just have to look and put the answer.

[@trinityhamied]

The alternate segment theorem is the angle between the chord and the tangent is equal to the opposite angle inside the triangle.

[@Bobbyaf]

Good job...but one slight error. At 44:55 the third figure isn't a cyclic quadrilateral inscribed in a circle. The figure inscribed is a 5-sided one and therefore cannot be used to determine angle 46 at the top. The angle of 134 does not belong to the cyclic quad.. To derive the 46 degree one would have to extend 2 radii from the centre to meet the chord above angle 134 degrees....and then find the reflex angle at the center which would be 2 x 134 = 268.....we then use the other angle at the center at the angle being 92. to derive the 46.....

[@ICOMATHS]

Thank you so much for the
spot on the minor error. I appreciate your feedback very much.

20:29 two diameters are intersecting it would create a 90 degrees at its intersection, shouldnt K be 36 and its adjacent angle is 54 so that if it was added it would form 90 degrees?

[@ICOMATHS]

I appreciate your question. However, we are dealing with a semicircle trangle at the circle which make angle 90 at the circumference. So k will naturally be 54 degree as calculated

Hey for the question in 9:07. TO solve DEB, Instead of doing what you did could you also do 180-90-65. Because an angle in a semi-circle = 90 ?

[@ICOMATHS]

Yes you can. However, the correct order will be 180 - (90 + 25) = 65

[@sheri-annashman3518]

Hello, I have a concern.
For number 9) where you are asked to find r and s I understand how you got the 23 and the 70 but for s wouldn’t you add the 70 and the 23 seen as angle s is from the quadrilateral and then there is a little part in the triangle?

At 5:54... arent the angles aod and abs both substended by the same arc/are in the same segment so they're both equal?

Thank you so much for the question. it seems so but not quite correct. Angles AOC and ABC are not on the same segment. Infact, angle AOC is not on a segment at all. it just subtends an angle at the centre O.

45:38 S will be 70 + 23 as it is not cyclic quadrilateral but a pentagon what he is taking

Hi I am a bit confused. For s shouldn’t the answer be 93? 70 + 23? As it is not just the angle opposite 110. At 45:21

[@ICOMATHS]

Thank you so much for your question. Apologies for replying late. Now i think there are two scenarios playing out here. The first is a cyclic quadriateral wherre the opposite angles are supplementary that is 180 degree. The second is an issoccles triangle where the base angles should be the same. In all those two scenarios i expalined how the various angles can be calculated following the rules
