∆ABC~∆LBN in ∆ABC AB IS 5.1 cm angle 40°, BC =4.8 cm AC=4/LN=7 Construct∆ ABC
Answers
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
