Question

Construct a right angle $△ABC$, right angled at $B$, when hypotenuse $CA=7.0cm$ and $AB=4.3cm$. Measure the length of $BC$.

Answer 1

1. Draw the base side $AB=4.3cm$
2. At point $B$, draw an angle of ${90}^{\circ }$
3. From $A$ cut an arc of length $AC=7.0cm$ using a compass
4. Name the point of intersection of the arm of the angle ${90}^{\circ }$ and the arc drawn in step 3, as $C$
5. Join $A$ to $C$
6. $ABC$ is the required triangle.
