# Thread: How do I construct this Triangle?

1. I have to construct the triangle "J" only using protractor, ruler, compass and pencil. But I can't seem to find a way to figure out the angles. Please help.

Hi schunck, and welcome to MHB!

Just to get you started, the two tangents from a point to a circle have the same length. So the line $AB$ is 13cm long, and a circle of radius 4cm touches it at a distance 6cm from $A$. Can you take it from there? (You don't need to know the angles.)
