00:02 Circles Theorem:If circles are drawn taking two sides of a triangle as diameters, prove that the point of intersection of these circles lie on the third side.
00:59 Triangle Inscribed in a semi circle is Right angles triangle.
01:04 Apply Linear Pair

In this video
students learn and solve aplication of Circles theorems (Several Theorems) and sample problems relating circles and associated angles.

Circles theorem 5. The line drawn through the centre of a circle to bisect a chord is perpendicular to the chord.
Circles theorem 6. There is one and only one circle passing through three non-collinear points.
Circles theorem 9. If two arcs of a circle are congruent, then their corresponding chords are equal and conversely if two chords of a circle are equal, then their corresponding arcs (minor, major) are congruent.
Circles theorem 10. Congruent arcs of a circle subtend equal angles at the centre.
Circles theorem 11. The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle.
Circles theorem 12. Angles in the same segment of a circle are equal.
Circles theorem 13. Angle in a semicircle is a right angle.

@kklaster

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

@ordmiss

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral
