Question

Which of the following angles can be

constructed using ruler and compass only ?

(A) 25º (B) 50º

(C) 22.5º (D) 42.5º​

Answer 1

Answer:

C

Step-by-step explanation:

{ yeah, 22.5 is the correct one which is too constructed by the ruler &the compass

1 . At first , draw the line segment PQ

2 . By using the segment draw the semi-circle

3 . With the semi-circle draw the 90° with the

usage of the ruler

4 . By that it has formed the two right angled

triangles.....

5 . By using the ruler & compass bisect the

90° angle

6 . Then ,90÷2 = 45 then each angle is 45°

7 . After bisect the 45° angle too 45÷2 = 22.5°

It is the way of the angle formed!!!!
