Out-of-bounds relief became an issue with my card Sunday morning at Frostbreaker. Bumping thread to bring a visual aid to the discussion we had.

This is meant to be a friendly reminder as to two out-of-bounds rules. Not busting nuts, just improving knowledge for all.

802.03 D

If the position of the thrown disc is in-bounds but within one meter of an out-of-bounds line, the lie may be marked by placing a mini marker disc on the playing surface at any point on a one-meter line that extends

**perpendicularly **from the nearest point on the out-of-bounds line and passes through the center of the thrown disc, even if the direction takes the lie closer to the target. For the purpose of marking the lie, the out-of-bounds line represents a vertical plane.

804.04 D

A player whose disc is out-of-bounds shall receive one penalty throw. The player may elect to play the next throw from:

The previous lie; or,

A lie that is up to one meter away from and

**perpendicular **to the point where the disc last crossed into out-of-bounds, even if the direction takes the lie closer to the target; or,

Within the designated drop zone, if provided.

The lie can only go towards the basket if it is perpendicular to the out-of-bounds line, the line itself being out-of-bounds.

...

The conversation ensued as to what 'perpendicular' meant.

Construction of the perpendicular (blue) to the line AB through the point P.

Perpendicular is determinable both on a straight line and a curved line.
