Question
A triangle has vertices A(0, 0), B, (–2, 8), and C(1, 7). What are the coordinates of the triangle after a dilation with a scale factor of 4?
Answer:
Basically multiply the x and y coordinates of each point by 1/2
For example, I’ll do C which is ( -2 , 10 )
-2 * 1/2 = -1 and 1/2 * 10 = 5
The new coordinate is ( -1 , 5 )
Now you can try the other points
Answer:
Step-by-step explanation:
mutiply x and y component by 4
A(0 , 0) = (4*0 ,,4*0)
A’ = (0 , 0)
B(-2 , 8) = (-2*4 , 8*4)
B’ = (-8 , 24)
C(1 , 7) = (1*4 , 4*7)
C’ = (4 , 28)
