dilated triangle.​

The vertices of the triangle are A 35 B 6 1 and C59 is dilated using a scale factor 2 Find the coordinates of thedilated triangle class=

Answer:

2nd choice

Step-by-step explanation:

How you have to is multiply the coordinates by 2 since the scale factor you want to dilate image at is at 2.

That is the pre-image is (x,y) and the image is (2x,2y) per each point.

A(3,5) becomes A'(3*2,5*2)=A'(6,10)

B(6,1) becomes B'(6*2,1*2)=B'(12,2)

C(5,9) becomes C'(5*2,9*2)=C'(10,18)

So 2nd choice.

The coordinates of the dilated triangle are (6,10) , (12,2) and (10,18)

What is scale factor?

The scale factor is a measure for similar figures, who look the same but have different scales or measures

How to find the coordinates of a dilated triangle?

  • To find the final coordinates we need to multiply the initial coordinates by the scale factor which is 2.
  • So for the coordinate A(3, 5),  the coordinate of the dilated triangle

A' = (3 x 2, 5 x 2) = (6, 10)

  • For the coordinate B (6, 1),  the coordinate of the dilated triangle

B' = (6 x 2, 1x 2) = (12,2)

Similarly C' will be (10 , 18)

So the coordinates of the dilated triangle are (6,10) , (12,2) and (10,18)

So option B is correct.
