End of Semester test geometry semester a question 29


Triangle DEF is dilated with respect to the origin by a scale factor of to produce ΔD'E'F'. What is the length of side D'E'?


A.

B.

C.

D.

Respuesta :

The resulting coordinate will be D'(2, 6), E'(4, -6), and F'(0, 10),

Let the coordinate of the triangle DF be given as D(1, 3), E(2, -3) and F(0, 5).

  • For instance, if the coordinate point (x, y) is dilated by a factor of k, the resulting coordinate will be (kx, ky)

  • Note that each of the coordinates is multiplied by the scale factor.

For the coordinates D(1, 3), E(2, -3), and F(0, 5), assuming the coordinate point is dilated by a factor of 2, the resulting coordinate will be D'(2, 6), E'(4, -6), and F'(0, 10),
