Geometrical constructions — practice question
$ABC$ forms a triangle, with $AC = 5\,\text{cm}$ and $BC = 7\,\text{cm}$.
(a)[2]
With only ruler and compasses, construct triangle $ABC$. The side $AB$ has already been drawn.
(b)[2]
With a straight edge and compasses only, draw the perpendicular bisector of $AB$.
(c)[1]
A point $W$ is located inside triangle $ABC$. Point $W$ is nearer to $A$ than to $B$. On your diagram, shade the region where $W$ is found.
