Fill in the blanks:(i) If two angles are complementary, then the sum of their measures is _______.(ii) If two angles are supplementary, then the sum of their measures is ______.(iii) Two angles forming a linear pair are _______________.(iv) If two adjacent angles are supplementary, they form a ___________.(v) If two lines intersect at a point, then the vertically opposite angles are always_____________.(vi) If two lines intersect at a point, and if one pair of vertically opposite angles areacute angles, then the other pair of vertically opposite angles are __________.

Explanation

Let's solve the question step by step:

### Step 1: Understanding Complementary Angles
- **Definition**: Two angles are said to be complementary if the sum of their measures is 90 degrees.
- **Fill in the blank**: If two angles are complementary, then the sum of their measures is **90 degrees**.

### Step 2: Understanding Supplementary Angles
- **Definition**: Two angles are said to be supplementary if the sum of their measures is 180 degrees.
