Question

How to construct angle 142.5

Answer 1

Construct 120 and 180 angles.
Bisect 120 and 180 and construct an angle of 150.
Now Bisect 150 and 120, u have 135
Finally, Bisect 135 and 150 and get 142.5

Don't be lazy and draw a line for each and every angle (120, 180, 150, 135 and 142.5)

If helps, please mark it as brainliest ^_^

Answer 2

First create an angle of 135 by creating angle of 120 and 150

You can create 150 by bisecting 120 and angle of 180

And then bisect 130 and 150
