Question

Polygon ABCD is translated to create polygon A′B′C′D′. Point A is located at (1, 5), and point A′ is located at (-2, 1). What is the distance from B to B′ ?

Answer 1

Any two corresponding points in the preimage and the image are the same distance apart (line segments AA′ = BB′ = CC′ = DD′). 5 units

Explanation:

Answer 2

The distance between B and B' will be the same as distance between A and A'.

= sqrt ( (5-1)^2 + ( 1 - -2)^2)

= sqrt (16 + 9)

= 5 units answer
