Draw a rough sketch of given measurements :
Steps of Construction
- First of all, we draw a line segment AB = 4.2 cm.
- Construct ∠BAX = 90° at point A with AB with the help of a pencil and compass. An arc of 2.5 cm. cut from AX. Put D at the cut point.
- Similarly, we construct ∠ABX = 90° with AB at point B and arc of 2.5 cm cut a point C from BY.
- Join CD.
Thus, we get required ABCD
Measures of AC and BD = 4.9 cm.
