Answer:
Step-by-step explanation:
Find the ratio..
small to large
2:6
so we increased by a factor of 3
We now know to increase by a factor of 3. Our center of dilation is point (3, 0). So we start there and and find the coordinates of the points of smaller triangle in relation to the center of dilation...
Basically how many units on the x, y axis is each point from (3, 0) which is center.
Small triangle=
(-1, 0)
(2, 1)
(1, -2)
So when multiplied by a factor of 3 we get...
larger triangle=
(-3, 0)
(6, 3)
(3, -6)
We multiplied the coordinate from small by 3. This means for larger triangle we start at center of dilation, (3, 0) and move the number of units shown in our coordinates for larger triangle from center to plot points.
