Paste the angle abc on ruled sheet such that the base of the triangle coincides with ruled line Mark two points P and Q on AB and AC such that PQ||BC. Using a ruler measure the length of AP, PB, AQ, and QC. Repeat the same for right angle triangle and obtuse angle triangle. Now observe the following observation table RESULT In each set of triangles we verify t...
