Question

Write the converse of each of the following statements.
(i) If the sum of measures of angles in a figure is 1800, then the figure is a triangle.
(ii) If the sum of measures of two angles is 900 then they are complement of each other.
(iii) If the corresponding angles formed by a transversal of two lines are congruent then
the two lines are parallel.
(iv) If the sum of the digits of a number is divisible by 3 then the number is divisible
by 3.
