Question

construct triangle ABC in which AC=7cm , angle B= 60 construct it's in circle m​

Answer 1

Step-by-step explanation:

Steps of Construction:

1 Draw a line segment BC = 7cm

2 Construct ZCBX = 60°

3 Draw OB 1 BX intersecting the perpendicular

bisector of BC at O.

4 With O as centre and radius OB or OC draw a

circle.

5 Cut DN = 3.7 cm

6 Through N draw I on DN intersecting the circle at

the point A and A'.

7 Join AB, AC and A'B, A'C

8.. AABC and ΔΑΒC are the required triangles Hence, the number of possible triangles = 2.

Answer 2

Steps of Construction :

1 Draw a line segment BC=7 cm

2 Construct ∠CBX=60

∘

3 Draw OB⊥BX intersecting the perpendicular bisector of BC at O.

4 With O as centre and radius OB or OC draw a circle.

5 Cut DN=3.7 cm

6 Through N draw ⊥ on DN intersecting the circle at the point A and A
