    I honestly was having a very hard time in finding angles as well as proving of course, but ever since I started watching your videos I'm confidently and proudly saying I now understand Euclidean though i have to do more practice to familiarise myself with it like you always say. I appreciate it, thank you sir, your efforts mean a lot🙏🏾

    In this video, the first example after theorem 9, both the angles are at the circumference but no equal why?
    One is 35 and one is 70 ,what's the difference

    Thank you for explaining the first part. It is the most confused part, the tangents, secants and line segments and arcs. And it seems you deliberately jumped the hardest theorem of them all, theorem 4 and its corollaries. Great lesson though much appreciated

    • @MlungisiNkosi
      @MlungisiNkosi  2 ปีที่แล้ว +2

      Thank you for the compliment… I didn’t skip theorem 4 . It must’ve happened been an error that happened upon edit. We end up with so many files that it ends up getting confusing at times. I wish you could see the process
      I don’t deliberately skip anything because I created this channel to bridge that gap. I’m glad that I have people like you to keep me in check from a content perspective.
      Thank you for the comment 😊

    sir, for example 2 would it be incorrect to first find angle p (angles of a straight line by subtracting 180-120=60) and since angle y is =90 (exterior angles of a cyclicquad) can i find z by angles of a triangle (60+90+z=180)?

    On example no 2 on finding z can I say that
    P+s+q =180° ( sum of < of a triangle)
    120° +s +90°=180°
    S = 30°
    Z = 30°
    Is it correct?
