Construct a ΔABC in which B = 30°, C = 60° and the length of the perpendicular from the vertex A to the base BC is 4.8 cm.

Steps of Construction


1. Draw a line segment XY.


2. Take any point P on XY and draw PQXY.


3. Along PQ, set off PA= 4.8 cm.



4. Through A, draw LMXY.


5. Construct LAB=30° and MAC = 60° meeting XY at B and C respectively.

Therefore, ΔABC is the required triangle.
