Perpendicular lines have a right angle (90°) between them. You can use the Perpendicular constraint between sketch elements.
To create a Perpendicular constraint:
- Select two lines.
- From the constraints menu, select Perpendicular.
Lines do not need to share a common point or intersect with each other to be made perpendicular. Guide curves are shown to indicate a perpendicularity between disconnected lines.
