Brad will put fencing around a circular
area in his yard for some baby goats he
purchased. If the circular area will have
a radius of 10 feet, how many feet of
fencing will Brad need?

Radii ok and nl are perpendicular to om because of the radius-tangent theorem. by definition of perpendicular, angles kom and lnm are right angles. this means that triangles kom and lnm are right triangles. angle lmn is common to both right triangles, so by the triangles kom and lnm are similar.
