Question

Which image shows triangle ABC dilated by a scale factor of 3 centered at the point B

Answer 1

If triangle ABC undergoes a dilation of scale factor 3 centered at the origin, the coordinate of the image of point B is known to be option D. (6,9).

What is the dilation about?

The term Dilation is known to be a kind of a transformation, that is used to change the size of an object.

Note that Point B has coordinates of (2, 3)

So the Dilation factor 3 will alter the coordinates as:

(2*3, 3*3)

= (6, 9)

Hence, If triangle ABC undergoes a dilation of scale factor 3 centered at the origin, the coordinate of the image of point B is known to be option D. (6,9).
