[aneeb2007]

sir you really are a good teacher but i wanna know one thing and that is how to find values in question like this FOR INSTANCE find angle ADO AND AOG. WHAT TO DO IN THESE TYPE OF QUESTION IS THERE ANY FORMULA TELL ME PLEASE

[lnmc]

Dear Aneeb,

When the question says "Find the angle ADO..... Start at A go to D then O. The angle forms at D, the middle letter. Angle APT means the angle forms at P, the middle letter. OK ? Watch some of my other lessons. You will understand.

You need to learn the laws first, then its simply applying them. Thank you for your comment.

Kind Regards

A question I have, in the second circle you show Sir, the quadrilateral is in a semi-circle.

Does the rule still apply?

Thanks.

[lnmc]

Dear qqqqqqqq,

As long as the four vertices touch the circle it is called cyclic quadrilateral and therefore the rule applies. OK.

Kind Regards

Now, the problem in my MATH in this CHAPTER is solved.

[ImpersonalUniverse]

this is awesome, something useful on youtube

[Arstel]

Thank you for the pleasant clear explanations & charts.

Best regards! :)

(PS: Btw, A few inspiring ancient geometry fractions... 22/7 = pi, 55/34 = phi, 14/11=sqrt phi; Squares diameter inscribed in circle = 7/10 circle diameter.) :-)

opposite angles in a quadrilateral dont ALWAYS add up to 180 deg.

[lnmc]

YOU ARE RIGHT. OPPOSIT ANGLES IN A QUADRILATERAL DONT ALWAYS ADD UP TO 180 deg.

OPPOSIT ANGLES IN A "CYCLIC QUADRILATERAL" ALWAYS ADD UP TO 180 deg. Good observation. Thanks for your comment.

kind regards
