When constructing a perpendicular to a line through a point ON the line, what tool combination is required?
Show answer
A ruler and compasses.
What is the difference between 'constructing a perpendicular TO a line through a point' versus 'constructing a perpendicular FROM a line to a point'?
Show answer
The first case has the point ON the line; the second case has the point OFF the line (external to it).
In geometric constructions with ruler and compasses, what does 'perpendicular to AB through point C' mean when C is on AB?
Show answer
A line through C that meets AB at a right angle (90°).
In geometric constructions with ruler and compasses, what does 'perpendicular from line GH to point I' mean when I is not on GH?
Show answer
A line from I that meets GH at a right angle (90°).
