Geometry Chapter 2 Drawing Angles With Compass
Question 1. Draw the following angles using a scale, pencil 1350, and compass.
- 1.5°
- \(22 \frac{1}{2}^{\circ}\)
- 30°
- 45°
- 60°
- \(7 \frac{1}{2}^{\circ}\)
- 75°
- 90°
- 105°
- 120°
- 135°
- 150°
Solution:
∠AOB = \(7 \frac{1}{2}^{\circ}\)
∠AOC = 15°

Question 2. Draw an angle ABC where ∠ABC = 45° Then CB is produced to any point D. Measure the LABD using a protractor. Bisects the ∠ABC and LABD wring compass and measures the angle between the bisectors of ∠ABC and ∠ABD.
Solution:
∠ABC= 45°
∠ABD = 15°
Angle between the bisectors of ∠ABC and ∠ABD = \(37\frac{1}{2}\)
