# Round 'n Round We Go

Geometry Level 4

A kid draws a series of triangles as shown in the figure above. The first triangle he draws has legs 1 and 1. All the triangles that he draws are right angled with base 1.

The last triangle that he can draw without overlapping the first one is the $$n^\text{th}$$ triangle.

Then he overlaps the first triangle and continues drawing.

The last triangle he can draw without overlapping the first one again, is the $$m^\text{th}$$ triangle.

Find $$n+m$$.
