Answer :

False,


Given:


Ratio of interior angles = 1:2:3


Let the interior angles be x, 2x and 3x


Now, the sum of the interior angles of the triangle are 1800


x+ 2x + 3x = 1800


6x = 1800


x =


x = 300


Therefore, the interior angles are: 300, 600 and 900.


Now, the exterior angles will be found by subtracting from 1800 because they form a linear pair.


The exterior angles are: 1500, 1200 and 900.
