Question

In the given figures, ∆ABC ~ ∆DEF, then find the unknown value x.

  1. 12
  2. 18
  3. 24
  4. 16

hintHint:

Two triangles △ABC and △DEF are similar (written as △ABC ∼ △DEF) if all three corresponding angles are equal. and the sides are proportional

The correct answer is: 12


    Two triangles △ABC and △DEF are similar (written as △ABC ∼ △DEF) if all three corresponding angles are equal. and the sides are proportional
    So,
    AB over DE equals BC over EF
8 over straight x equals 6 over 9
straight x space equals space 12

    If the scale factor is 1 third, the dilation is

    Scale factor : Scale Factor is defined as the ratio of the size of the new image to the size of the old image
    • If the scale factor is greater than 1, the image is an enlargement. It expands.
