Question

Construct $\Delta ABC$ in which $AB=AC,BC=3.8$ cm and $AD$ the altitude from $A$ to $BC=4.3$ cm.

Answer 1

Given: $ABC$ is a triangle, $AB=AC$ and $BC=3.8$ cm , $AD\perp BC,AD=4.3$
To construct : $\Delta ABC$
Steps of construction :
1. Draw a straight line $BC=3.8$ cm.
2. Draw the perpendicular bisector $AX$.
3. From $D$, cut off $DA=4.3$ cm.
4. Join BA and CA. Hence, $\Delta ABC$ is the required triangle.
