2. In the sketch O is the centre of the circle and AOB is a diameter. Therefore are ACB is a below.: semi-circle, and C is an angle in a semi-circle. Now follow the following steps to draw and mcasurc Mcasure C and record your value in the table C two more angies in semicircle ACB: • Choose any other point on semicircle ACB and name it point D. Draw AD and BD. Measure D. Choose a third point on semicircle ACB and name it point E. Draw AE and BD. Measure E. Angle Size

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
