Sergio039 [100]

Answer:

The distance from B to B' is 5 units

Step-by-step explanation:

The complete question is

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'?

we know that

In a translation the figure maintains its dimensions and internal angles

so

AA'=BB'=CC'=DD'

The distance BB' is the same that the distance AA'

<em>Find the distance AA'</em>

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

A(1,5),A'(-2,1)

substitute in the formula

AA'=\sqrt{(1-5)^{2}+(-2-1)^{2}}

AA'=\sqrt{(-4)^{2}+(-3)^{2}}

AA'=\sqrt{25}

AA'=5\ units

therefore

The distance from B to B' is 5 units
