Question

Construct a quadrilateral ABCD with three sides AB = 5 cm, BC = 5.6 cm, AD = 4.8cm and two diagonals AC = 7cm and BD = 5.8 cm.




Q2. Factorise:(i)bm–pq+qb–pm(ii)7(p+2)2 –9(p+2)

Answer 1

Draw a line segment AB = 5cm.

⇒ With A as a center and radius AC = 5cm, draw an arc.

⇒ With B as a center and radius BC = 6cm, draw an arc, intersecting the previous arc at point C.

⇒ With A as a center and radius AD = 3cm, draw an arc.

⇒ Take C as a center with radius CD = 4cm draw an arc intersecting the previous arc at point D.

⇒ Join AC, BC, AD and CD.

Thus, ABCD is a required quadrilateral.
