Q12 of 168 Page 5

In , it is being given that: AB = 5 cm, BC = 4 cm and CA = 4.2 cm; DE = 10 cm, EF = 8 cm and FD = 8.4 cm. If and , find AL : DM.

Since = = =


Then, ΔABC ~ ΔDEF (By SS similarity)


Now, In ΔABL ~ ΔDEM


<B = <E (ΔABC ~ΔDEF)


<ALB =<DME (Each 90°)


Then, ΔABL ~ ΔDEM (By SS similarity)


So, (Corresponding parts of similar triangle area proportion)


Or


Or,
