Question

triangle ABC ~triangle LBN in triangle ABC ,AB=5.1cm ,angleB =40°,BC=4.8cm AC/LN =4/7 construct triangle ABC and triangle LBN​

Answer 1

Step-by-step explanation:

Hence the required construction

Steps of construction:

Draw a line segment BC with a scale of 4.8 cm

From point B measure an angle 40°.

From point B with a measure of 5.1 cm draw an arc along the angle marked.

Mark the point as A

Join AB and AC.

Hence the required Δ ABC.

Divide the line segment BC into 4 equal parts. (4.8 ÷ 4 = 1.2 cm)

Mark a point N on the line segment BC such that BN is seven times the of each segment BC.

Draw a line parallel to AC, through N.

Name the point of line as L.

Join LN.

Hence the required Δ LBN
