Draw any line segment ^@ \overline{ AB }. ^@ Mark any point ^@ M ^@ on it. Through ^@ M, ^@ draw a perpendicular to ^@ \overline{ AB }. ^@
Answer:
- Draw a line segment ^@ AB ^@ and mark a point ^@ M ^@ on it.
- With ^@ M ^@ as centre and a convenient radius, construct an arc intersecting the line segment ^@ AB ^@ at ^@ P ^@ and ^@ Q. ^@
- With ^@ P ^@ and ^@ Q ^@ as centres and radius greater than ^@ PM, ^@ construct ^@ 2 ^@ arcs and mark the point of their intersection as ^@ K. ^@ Join ^@ MK. ^@
- ^@ \overline{ MK } ^@ is the required perpendicular through ^@ M ^@ on ^@ \overline{ AB }. ^@
