Answer 1

Unfortunately this is 4 steps:

1 to draw the radius on either side of the point, 2 to mark the points above, and 1 to actually draw in the perpendicular line.

Answer 2

m8 this sounds very hard

Answer 3

You also need 1 L only right?

Answer 4

For 1 L, there is one simple idea.. mark any two points on the line.. Then construct the angle bisector

Answer 5

But that would make 4 E... hmm...

Answer 6

Yeah this is my problem exactly haha.

Answer 7

3E seems impossible to me.

Answer 8

NO IT'S POSSIBLE :o WOAH!!!!! :P

Answer 9

I think I got it :P

Answer 10

Hahaha ok I am waiting to be amazed xD

Answer 11

Got it :D

Answer 12

1. We take some random point outside the line

Answer 13

Then we construct a circle from that point to the point we want to erect perpendicular at
