Write down the measures of
(a) some acute angles.               (b) some obtuse angles.
(give at least two examples of each).

(a) We know that the measure of an acute angle is less than 90degrees. So, 35 degrees, 40 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees all are acute angle.

(b) We know that the measure of an obtuse angle is more than 90 degrees. So, 110 degrees, 120 degrees, 125 degrees, 135 degrees, 140 degrees all are obtuse angle.
