Geometrical constructions — practice question
A triangle-shaped field, $ABC$, is given.
$AC = 500\text{ m}$ and $BC = 650\text{ m}$.
With only a ruler and compasses, finish the scale drawing of field $ABC$.
Keep the construction arcs visible.
Work to a scale where 1 cm represents 100 m.
The side $AB$ has already been drawn.
Diagram text: A straight line joins the points marked $A$ and $B$. The label says: "Scale: 1 cm to 100 m".
