Pythagoras identities are use to convert trigonometric ratio from one form to another. Also we use right angle triangle for conversion.
Conversion of Trigonometric RatioNon-right angle triangle . triangle that is not a right triangle is an oblique triangle. Solving an oblique triangle means finding the measurements of all three angles and all three sides. Non right angle triangle
The sine rule and cosine rule . The sine rule is used when we are given either a) two angles and one side, or b) two sides and a non-included angle. The cosine rule is used when we are given either a) three sides or b) two sides and the included Sine and cosine rule
Sine and Cosine Rule. Non right angle triangle can be done with the Law of Sine and Law of Cosine. Hence we apply this concept for non right-angle triangle. Also we apply for angle when three sides given. Sine and Cosine Rules.
