Hey, Check out these questions. 1. The point P lies within the angle ABC and is equidistant from AB and BC. Prove that PB bisects the ∠ABC. If point P is always equidistant from AB and BC, does that mean AB and BC are the same length? If so, that would produce congruent triangles correct? 2. A fence post 4.5 m high casts a shadow of 2.75 m. At the same time a nearby lamp post cast a shadow 13.75 m in length. Find the height of the lamp post. I need help getting started on this one, I think it has something to do with similar triangles. Thanks in advance.
