Question

Construct a triangle $ABC,$ whose base $BC=6cm,\angle B={60}^o$ and altitude $AD=4$cm.

Answer 1

Follow these steps for construction:

1. Draw the base $BC=6cm$.

2. Construct $\angle B={60}^o$ and extend the line $BX$.

3. With radius as $4cm,$ cut arcs at various points from $BC$. The line joining these arcs is parallel to $BC$ at a distance of $4cm$.

4. Name the point of intersection of $BX$ and the parallel line to $BC$ as $A$ and join $AC$.

6. $△ABC$ is the required triangle
