draw a line segment AB=8.5cm and divide it in the ratio 3:4
Answers
Answer:
Step-by-step explanation:
iven: Length of line segment 7.6 cm and ratio 5 : 8 i.e., m : n.
Step-by-step Construction:
Step 1: Draw a line segment AB of length 7.6 cm.
Step 2: Draw any ray AX, making an acute angle with AB.
Step 3: Locate 13 ( = m + n ) points A_1\,,\,A_2\,,\,A_3\,,\,A_4\,,\,A_5\,,\,A_6\,,\,A_7\,,\,A_8\,,\,A_9\,,\,A_{10}\,,\,A_{11}\,,\,A_{12}\,,\,A_{13}A

intersecting AB at the point C.
So, we get
⇒ AC : CB = 5 : 8
⇒ AC = 2.9 cm and CB = 4.7 cm
