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 ๐ด_1, ใ€– ๐ดใ€—_2, ๐ด_3, ๐ด_4, ๐ด_5 on AX such that ใ€–๐ด๐ดใ€—_1=๐ด_1 ๐ด_2=๐ด_2 ๐ด_3โ€ฆโ€ฆ. by drawing equal arcs Join ใ€–๐ต๐ดใ€—_5. Since we want the ratio 2 : 3, Through point ๐ด_2 (m = 2), we draw a line parallel to ๐ด_5 ๐ต by making โˆ  AA5B = โˆ  AA2C So, we copy โˆ  AA5B from point A5 Thus, AC : CB = 2 : 3. On measuring AC and BC by scale. AC = 3.2 cm & BC = 4.8 cm
