Triangle CAT is located at C (-5, 2), A (-4, 4), T (-1, 2). Find the coordinates of its image after a dilation with a scale factor of 4.
19. Square ABCD was dilated to form square A’B’C’D’. What scale factor was used?
20. Tell whether the pair of polygons is similar. Explain why or why not.
You have to multiply the x coordinates and the y coordinates each by 4 because 4 is the scale factor
But these are the answers
C (-20, 8), A(-16, 16), T (-4, 8)
@anonymous are u sure these are correct?
To find the coordinates of the image of a triangle after dilation with a scale factor of 4, you can multiply the coordinates of each point by the scale factor.
For Triangle CAT, the coordinates are:
C (-5, 2)
A (-4, 4)
T (-1, 2)
To find the image of each point, multiply the x and y coordinates by the scale factor of 4:
C' = (-5*4, 2*4) = (-20, 8)
A' = (-4*4, 4*4) = (-16, 16)
T' = (-1*4, 2*4) = (-4, 8)
Therefore, the coordinates of the image of Triangle CAT after a dilation with a scale factor of 4 are:
C' (-20, 8)
A' (-16, 16)
T' (-4, 8)
