The angles of a triangle are in AP and the least angle is 30^(@). What is the greatest angle (in radian) ?
we need to understand what is 'S' and 'A'. S = side A= angle To prove the triangles are congruent we use SSS SAS ASA AAS RHS SSS = side side side : 3 sides are equal we can prove they are congruent triangle. SAS = side angle side : 2 sides and 1 included angle ...
