Question 1139975
<br>
Find the distances in the x and y directions from the center of the dilation to each given vertex.<br>
Then multiply each of those distances by the scale factor 1/2 to find the corresponding distances from the center to each vertex of the dilated triangle.<br>
Finally move those new distances from the center to find the vertices of the dilated triangle.<br>
For example....<br>
The distances in the x and y directions from the center (-2,-5) to point A(-2,4) are 0 and 9.  Multiply those distances by 1/2 to get 0 and 4.5.  Move those new distances from the center to find the coordinates of A'.<br>
x: -2+0 = -2
y: -5+4.5 = -0.5<br>
A'(-2,-0.5)<br>
Do the same thing to find B' and C'.
