Question

Draw a right triangle in which the sides (other than hypotenuse) are of lengths 4 cm and 3 cm. Then construct another triangle whose sides are $5 over 3$ times the corresponding sides of the given triangle.

Solution

Steps of Construction :
(i) Draw line BC = 4 cm.
(ii) Draw BA = 3 cm line segment with 90° at B.

(iii)    Join AC to form right ΔABC.
(iv)    Construct an acute ∠CBX downwards.
(v)    Along BX mark off 5 equal points B₁, B₂, B₃, B₄, B₅ such that BB₁ = B₁B₂=... = B₄B₅.
(vi)    Join C to B₃ and draw a line through B₅ parallel to B₃C intersecting the extended line segment BC at C’.
(vii)    Again we draw C’A’ parallel to AC.Thus, ΔA‘BC’ is the required triangle.
