Q8 of 45 Page 476

Construct a ΔABC in which ∠B = 60°, ∠C = 45° and the length of perpendicular from vertex A to base BC as 5 cm.

Steps of Construction


1. Draw a line segment XY.


2. Take any point P on XY and draw PQ⊥XY.


3. Along PQ, set off PA= 5 cm

4. Through A, draw LM∥XY.


5. Construct ∠LAB=60° and ∠MAC=45° meeting XY at B and C respectively.
