Hello Candidate,
Let one angle of the triangle is x degree.
Now according to the question the angles are in ration 1:2:1.
Hence clearly the angles are x, 2x and x
Now we know that the sum of angles of any triangle is equal to 180 degree.
so clearly x + 2x + x = 180
hence x = 45 '
So the angles of triangle are listed below 45', 90', 45'
Hope it helps.
