Circle Theorems Part 2 | Geometry & Measures | Maths | FuseSchool

Let’s discover some more circle theorems so that we can solve all types of geometrical puzzles.

We discovered these 4 theorems in part 1:
Angle at the centre is double the angle at the circumference
The angle in a semi-circle is 90 degrees
Angles in the same segment are equal / Angles subtended by the same arc are equal
Opposite angles in a cyclic quadrilateral add up to 180 degrees.

Watch part 3 to discover the final 2 theorems that involve intersecting chords.

I wanna ask. In the 3rd question its says that the answer is 64. But when i add angle DAB=64, angle ADB=32 and angle DBA=32 it doesn't make 180 degrees since DAB is a triangle can you pls explain it to me?

If you speak faster you'd sound easier to listen to. Ik because I sped it up 1.25x, and I only sped it up because you were speaking unnaturally slow. Great vid though
