Question

4) The vertices of APOR have coordinates P(2,3),(3,8), and R(7,3). Under which transformation ofAPQR are distance and angle measure preserved?1) (x,y) → (2x, 3y)2) (x,y) → (x + 2,3y)3) (x,y) → (2x,y+3)4) (x,y) → (x+2y+3)

Answer 1

Problem

solution

1) Is not correct since we have a different scale factor for x and y

2) Is not correct since we apply a shift 2 units to the left and a dilation factor of 3 distance is not preserned

3) Is not correct since we have a dilation factor of 2 for x and a shift 3 units up then distance is not preserved

4) Is correct since we apply a shift 2 units
