doing this. In order to master the techniques explained here it is vital that you undertake the practice exercises provided. After reading this text, and/or viewing the video tutorial on this topic, you should be able to: • solve triangles using the cosine formulae. • solve triangles using the sine formulae. • find areas of triangles.
Acquire the concepts of solution of triangles including properties of triangles and triangle formulas with the help of study material for IIT-JEE by askIITians.
6 Apr 2013 ORTHOCENTER AND PEDAL TRIANGLE The triangle KLM which is formed by joining the feet of the altitudes is called the Pedal Triangle. Its angles are - 2A, - 2B and - 2C. Its sides are a cosA = R sin 2A, b cosB = R sin 2B and c cosC = R sin 2C Circumradii of the triangles PBC, PCA, PAB and ABC
