<h3>Q2</h3>
  • ΔABC~ΔDEC

<u>Ratios of corresponding sides are equal:</u>

  • DE/AB = DC/AC
  • DE/40 = 15/(15 +9)
  • DE = 40*15/24
  • DE = 25
<h3>Q3</h3>
  • ΔABD~ΔBCD

<u>Ratios:</u>

  • AD/BD = BD/DC
  • AD*DC = BD²
  • 16*(20 - 16) = BD²
  • 64 = BD²
  • 8 = BD
<h3>Q4</h3>

<u>If ΔABC ~ ΔXYZ, the ratios below should be equal:</u>

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

Ratios are different so the triangles are <u>not</u> similar
