To do:

We have to fill in the blanks.
Solution:

(a) An angle whose measure is less than that of a right angle is an acute angle.

(b) An angle whose measure is greater than that of a right angle is an obtuse angle.

(c) An angle whose measure is the sum of the measures of two right angles is a straight angle.

(d) When the sum of the measures of two angles is that of a right angle, then each one of them is an acute angle.

(e) When the sum of the measures of two angles is that of a straight angle and if one of them is acute then the other should be an obtuse angle.
