    *MUST READ* Number six in this video apears to be out of proportion and I did not realise. the arrow head shape MUST join in the centre of the circle not just anywhere. please note that the angle at the CENTRE of the circle is double that at the tip of the arrow.
    in the video it is slightly below the centre of the circle.

    Also, for 1:47 , it doesn't have to be an arrow shape.
    It's just that all angles from the centre of the circle will ALWAYS be twice (2x) the angle at the circumference, as long as they are subtended by the same arc. The angle at the circumference can move around the circumference, making shapes that don't have names.

    For that question at the end, there is a much quicker way to do it.

    Therefore, D = 55 degrees because of alternate segment theorem

    Here's one more little tip: in the last question, the quadrilateral ABC and the 70° point make up a cyclic quadrilateral (proof left as an exercise) so C is 180° - 70° = 110°. Then you can proceed as in the video to get D = 110° / 2 = 55°.

    • @Aiden-xn6wo
      @Aiden-xn6wo 3 года назад +3

      Actually I used a completely different method:
      Let the intersection of the tangents be point P, and the points where the circle touches the tangents be Q and R.
      Then PQ=PR, so triangle PQR is an isosceles triangle.

    • @Aiden-xn6wo

      the literal definition of a cyclic quadrilateral is "a cyclic quadrilateral is a quadrilateral whose vertices all lie on a single circle." here angle 70 degree lies outside the circle, so this is not the right method of doing this sum.

    • @Aiden-xn6wo
      @Aiden-xn6wo 2 года назад +1

      ​@@AD-il9zs That is a correct definition, but your argument is incorrect.

    For those who didn't understand.. tangents: Tangents touching the circle are equal so ... angle A and other angle is equal since it forms isosceles angle (if 2 sides are equal then the angle opposite to sides are equal.)
    Step 1: 2x+70= 180....x= 55
    Step2 : tangent touching the circle forms 90° so 55°+interior angle B = 90
    So interior angle B is 35°
    Step3 : line BC and AC are radius so it will same or equal ... again it forms isosceles triangle so Interior angle B and interior angle A will 35° ...so angle C will be 110°
    Step 4 : Angle D will b half of Angle C so D will be 55° (Angle subtended by arc and Central Angle theorem....shown in the video)

    You can also solve using this

    We get angle C = 110°
    Now angle subtended by a arc at centre is double the angle subtended by it at any point on circle

    A + B + 70 = 180 (Sum of angl...)
    A + B = 180 - 70 = 110
    A = B (Equal lengths of the 2 sides = Isosceles therefore base angles are equal, 110/2 = 55 each)
    A = D = 55 (Tan chord theorem OR theorem 9 in the video)

    2:54 as two angles between the tangent makes 70 °so the angle between radius ie angle C=180°-70°= 110°. Now as it is the angle subtended by the arcs at centre,so angle D= C/2 = 55 °

    By the way the length A B and A C were put in the wrong place when i rendered the video. Length A B and A C are meant to be from the start of the tangent to where it hits the circle, not at the end of the tangent because that line will go on for forever if it could!

    Ps. To the question at the end, there's a much simpler less painful method
    Instead of using circle theorems to find angle C, then using the angles in an arrow rules, you can find the answer directly after you find angle A using (180 - 70)/2,. You can simply use the alternate segment theorem to see that A is the same as angle D, getting the answer of 55 degrees.

      even easier if you go straight to c = 110 because 360 - 70 - 90 - 90 because tangent meets radius at 90 degrees and angles in a quadrilateral add up to 360. Then you do angle in middle is twice angle at circumference

    Actually you can solve the final question with only two steps:

    2) Angle D = Angle A (Alternate segment theorem)
    That's it
