# If the angles of

Given: Angles of a triangle are in the ratio 1 : 2 : 3

Need to prove: Its corresponding sides are in the ratio

Let the angles are x , 2x , 3x

Therefore, x + 2x + 3x = 1800

6x = 1800

x = 300

So, the angles are 300 , 600 , 900

So, the ratio of the corresponding sides are:

= sin300 : sin600 : sin900

=

= [Proved]
