**Question 7. State which of the following angles with a small letter in the following diagrams are acute, which obtuse and which are reflex:**

**Answer:**

(i) ∠a and ∠c are acute, ∠h is obtuse

(ii) ∠x and ∠z are obtuse, ∠y is acute.

(iii) ∠p is obtuse, ∠q and ∠s are acute, ∠r is reflex.

**Question 8. Use your protector to measure each of the angles marked in the following figures:**

**Answer:**

(i) 62°

(ii) 116°

(iii) 121°

**Question 9. Use your protector to measure the reflex angles marked in the following figures:**

(ii) 235°

**Question 10. Find the measure of the angle between the hands of the clock in each figure:**

**Answer:**

(i) 60°

(ii) 30°

(iii) 150°

**Question 11. Write the measure of the smaller angle formed by the hour and the minutes hands of a clock at 7 O’clock. Also write the measure of the other angle and also state what types of angles these are.**

**Answer:**

Smaller angle is 150° (obtuse).

The other angle is 210° (reflex).

**Question 12. There are two set-squares in your geometry box. What are measures of the angles formed at their corners? Do they have any angle measure that is common?**

**Answer:**

One is a 30° – 60° – 90° set square; the other is 45° – 45° – 90° set square. The angle of measure 90° (i.e., a right angle) is common between them.
