Question

A teacher asked her students to construct a quadrilateral ABCD with AB = 12 cm, BC = 9cm, LA = 60°, LB = 105° and LC = 105°. A student performed the following steps of construction. Step 1: Draw AB = 12 cm. Step 2: Taking B as the centre, draw LABE = 105°. Step 3: Taking A as the centre and radius equal to 9 cm, draw an arc intersecting BE at C. Step 4: Taking A as the centre, draw LBAF = 105°. Step 5: Taking C as the centre, draw LBCG = 60°. The student made an error while constructing the quadrilateral. In which step did the student make the first error?


a.)Step 5
b.)Step 4
c.)Step 3
d.)Step 2​
