Question

To construct a ${135}^{\circ }$ angle using a compass and ruler only, angles are required to be constructed.

• A. 110° & 25°
• B. 65°& 70°
• C. 90°& 45°
• D. 100°& 35°

Answer 1

The correct option is C 90°& 45°

To construct an angle of ${135}^{\circ }$ using only a compass and ruler, we will first draw an angle of ${90}^{\circ }$ and then further an angle of ${45}^{\circ }$. When taken together, the resultant angle formed will be equal to ${135}^{\circ }.$
