Question 28 (OR 2nd question) Draw a line segment of length 8 cm and divide it in the ratio 2:3
Steps of construction:
Draw line segment AB of length 8 cm
Draw any ray AX,
making an acute angle with AB.
Mark 5 (= 2 + 3) points π΄_1, γ π΄γ_2, π΄_3, π΄_4, π΄_5 on AX such that γπ΄π΄γ_1=π΄_1 π΄_2=π΄_2 π΄_3β¦β¦. by drawing equal arcs
Join γπ΅π΄γ_5.
Since we want the ratio 2 : 3,
Through point π΄_2 (m = 2), we draw a line parallel to π΄_5 π΅
by making β AA5B = β AA2C
So, we copy β AA5B from point A5
Thus, AC : CB = 2 : 3.
On measuring AC and BC by scale.
AC = 3.2 cm & BC = 4.8 cm
