Figure 05-10—Simplified difficulty symbols
This image portrays three distinct symbols within three separate boxes. Each box has a clear background.
The symbol within the box on the left is a green circle with a slightly wavy white line passing through the diameter. The legend above this box reads: Easiest DD-1.
The symbol within the middle box is a blue square with a more pronounced white wavy line passing through its center in an irregular shape. The wave forms a distinct trough on the left side of the square and a distinct crest on the right. The legend above this box reads: More Difficult DD-2.
The symbol within the box on the right is a black triangle with a jagged white line passing through its middle in a zigzag pattern. The line has two distinct troughs and two distinct crests moving from the left of the symbol to the right. The legend above this box reads: Most Difficult DD-3.
