Question

Construct the angle of following measurement using a scale (ruler) and compasses. Verify the angle using protractor: 135°

Answer 1

Solution:-

CONSTRUCT =>
1.draw a line OA.
2. O is a centre. now use compass and open it to any convenient redius. draw an arc which cuts line segment OA at B.
3. B is centre , again use compass and opened to same redius, draw an arc which cuts first arc at C.
4. c is centre . Again use compass and opened to the same radius , draw another arc which cuts first arc at D .
5. here C and D are centre. Again use compass and opened to the same radius, draw two arc which cuts each other at E .
6. Join OE and extent it to y
7. angle EOA = 90 DEGREE.
8. Again use compass and open it to any convenient radius. And with O as center.
9. here G and E are centre . Again use compass and opened to same radius , draw two arcs which cuts each other at point F.
10. join OF and extent to z.
●here angleZOA = 135 degree.
