Answer:

Q2

  • ΔABC~ΔDEC

Ratios of corresponding sides are equal:

  • DE/AB = DC/AC
  • DE/40 = 15/(15 +9)
  • DE = 40*15/24
  • DE = 25

Q3

  • ΔABD~ΔBCD

Ratios:

  • AD/BD = BD/DC
  • AD*DC = BD²
  • 16*(20 - 16) = BD²
  • 64 = BD²
  • 8 = BD

Q4

If ΔABC ~ ΔXYZ, the ratios below should be equal:

  • AC/XZ = BC/YZ
  • 10/15 = 18/24
  • 2/3 = 3/4

Ratios are different so the triangles are not similar
