There are some special cases in which we can construct the quadrilateral with less number of measurements also.
Construct a square READ with RE = 5.1 cm.
Given Re = 5.1 cm.
As it is a special quadrilateral called square, we can get more details out of it.
a. All sides of square are equal, so RE = EA = AD = RD = 5.1 cm.
b. All the angles of a square are 90°, so R = E = A = D = 90°
Step 1: Draw a rough sketch of the square.
Step 2: To construct a square, draw a line segment RE = 5.1 cm. Then draw the angle of 90° at both ends R and E of the line segment RE.
Step 3: As all the sides of the square READ are equal, draw the arc of 5.1 cm from the vertex R and E to cut the lines RD and EA respectively.
Step 4: Join A and D to make a line segment AD.
READ is the required square.
