What is M and L in GeometryDrawing?

What is the meaning of M and L in this code?

<GeometryDrawing x:Name=”Front” Brush=”R开发者_StackOverflowed”
Geometry=”M0,260 L0,600 L110,670 L110,500 L190,550 L190,710 L300,775

M is for move to, L is for line to, etc. You should check this link: https://learn.microsoft.com/en-us/dotnet/desktop/wpf/graphics-multimedia/shapes-and-basic-drawing-in-wpf-overview section XAML Abbreviated Syntax.
