## Drawing Trees

## Path in Trees

**Path** in a tree: a linear subset (e.g. A-B-E or C-F).

**Length** of a path: either count the nodes or the edges.

There is a unique path from the root to any node.

**Depth** or **Level** of a node: the length of this path.

**Depth** or **Height** of a tree: maximum depth of its
nodes.
