Question

∆ABC~∆PQR. In ∆ABC, AB = 6.3cm, BC = 7.2 cm. And AC = 5.1 cm Construct ∆ABC and ∆PQR such that PQ : AB = 3:4

Answer 1

Answer:

⇒ Draw a line segment AB=5.2cm

⇒ Take B as a center with radius 3.1cm and draw an arc.

⇒ Take A as a center with radius 4.2cm and draw an arc meeting previous arc at point C.

⇒ Again take A as a center with radius 4.7cm and draw an arc.

⇒ Take B as a center with radius 6.1cm and draw an arc meeting previous previous arc at point D.

⇒ Join BC,CD,AD,AC and BD.

⇒ Thus, ABCD is a required quadrilateral.

⇒ We have to measure the angle of ABC.

⇒ m∠ABC=54
