Question

how will you construct a rectangle of abcd if you know only the length ab and bc​

Answer 1

We have given the sides of rectangle which is AB = 8cm and Bc = 6cm
We know that opposite sides of rectangle are equal then
AB = DC =8cm and BC = AD = 6cm
Steps of construction :
⇒ Draw a line segment AB = 8cm
⇒ Since, we know all angles of rectangle are 90
∘
then construct an angle of 90
∘
at A and B.
⇒ Cut off AD and BC at 6cm.
⇒ Join CD.
Thus, we het the required rectangle ABCD.

Answer 2

Answer:

1. Draw the line segment AB and draw a straight line from B.

2. Take the measurement of BC in the compass and draw an arc from B cutting the straight line.

3. Mark the intersecting point as C.

4. Now take the measurement of AB in the compass and draw an arc from C.(Reason is given below)

5. Then take the measurement of BC in the compass and draw an arc from A.(Reason is given below)

6. Mark the intersecting point as D

Step-by-step explanation:

Reason for 4 :

Opposite sides of a rectangle is equal

Reason for 5 :

Opposite sides of a rectangle is equal
