so do you know that corresponding sides of similar triangles are proportional ?

Answer 8

yes

Answer 9

can you apply that in triangles ACM and BCM ?

Answer 10

oh, sorry i mentioned ABC and ACM earlier
it should be ACM and BCM

Answer 11

i see what you're getting at

Answer 12

if you equate corresponding sides as equal , you directly get CM^2 as AM*BM

Answer 13

sorry , proportional*

Answer 14

for part c) you take triangles ABC and BCM

Answer 15

i got AM=BM * x^2 where x was the reduction factor or ratio

Answer 16

what? how ?

Answer 17

oh i did substitution... but i also got your answer

Answer 18

good :)

Answer 19

thnx so much XD
