Question 189
Construct a rectangle whose one side is 3 cm and a diagonal is equal to 5 cm.
Answer: Option A
:
We know that, diagonals of a rectangle and opposite sides are equal.
All the angles of the rectangle are the right angles.
So, AC = 5 cm
AB = 3 cm
Steps of Construction
Step I Draw AB = 3 cm.
Step II Draw ray BX such that ∠ABX=90∘.
Step III Draw an arc such that AC = 5 cm.
Step IV With B as centre, draw an arc of radius 5 cm. With C as centre, draw another arc of radius 3 cm which intersects the first arc at a point, suppose D.
Step V Join CD and AD.
Thus, ABCD is required rectangle.
