"Question 1 Draw the following: The square READ with RE = 5.1 cm
Practical Geometry Page 68"
Answers
To construct a quadrilateral it is necessary to know at least 5 of its parts.
Measurement of 5 parts of a quadrilateral are sufficient to construct it in the following cases:
1. Four sides and one Diagonal.
2. Three sides and both diagonals.
3. Two adjacent sides and 3 angles.
4. Three sides and two included angles.
5. Four sides and one angle.
It is always convenient and helpful to draw a rough sketch of the quadrilateral and indicate the given measurements.
==========================================================
[ Figure is in the attachment]
Steps of construction:
(i) Draw line segment RE = 5.1 cm.
(ii) At point E, draw an angle of 90° and draw an arc of radius 5.1 cm, which intersects at point A.
(iii) At point R, draw an arc of radius 5.1 cm at point A, draw another arc of radius 5.1 cm which intersects the first arc at point D.
(iv) Join AD and RD.
It is the required square READ.
