Given below are the steps of construction to construct a quadrilateral ABCD where AB = 3.5 cm, BC = 5.5 cm, CD = 2.4 cm, AD = 6.3 cm and ∠A = 45°. Which of the following steps is INCORRECT ?
Step I : Draw AB = 3.5 cm and construct ∠BAX = 45°.
Step II : With A as centre and radius AD = 6.3 cm, cut off AD = 6.3 cm along AX.
Step III : Join BD. With D as centre and radius 2.4 cm, draw an arc.
Step IV : With B as centre and radius 2.4 cm, draw an arc to cut the arc drawn in above step at C. Join BC, CD to obtain the required quadrilateral ABCD.
AStep I
BStep II
CStep III
DStep IV
the correct answer should be answer D i.e. Step 4.
Ans 1:
Class : Class 6
Yes it should be Option (D) Step IV
Ans 2:
Class : Class 7
should be option D
Ans 3:
Class : Class 5
yes true...cuz the last line which it is telling to construct is not the actual one
Ans 4:
Class : Class 10
yes the option is D
Ans 5:
Class : Class 8
Ans 6:
Class : Class 10
Step 4 and 3 both are incorrect
Ans 7:
Class : Class 10
4 and 3 both are wrong as in 3rd one it says to join diagonals which is useless and 4th one you know why
