Question

construct an triangle abc with perimeter 12cm and b=30° and c=90°​

Answer 1

Step-by-step explanation:

Draw a line segment PQ = AB + BC + CA = 12 cm. Make ∠ LPQ= 45° and ∠ MQP = 60° Now bisect ∠ LPQ and ∠ MQP such that their bisectors meet at A. Draw perpendicular bisector of AP and AQ i.e. XY and ST intersecting PQ at B and C respectively. Join AB and AC.
