Triangle ABC is translated using the rule (x, y) ? (x + 1, y ? 4) to create triangle A?B?C?. If a line segment is drawn from point A to point A? and from point B to point B?, which statement would best describe the line segments drawn?

Respuesta :

Answer:

The line segments AA' and BB' are parallel and congruent

Step-by-step explanation:

we know that

When the transformation is a translation, the figure does not change its shape or dimensions,

so

AA'=BB'=CC'

therefore

The line segments AA' and BB' are parallel and congruent

Translation involves moving a function away from its original position.

The statement that describes the line segments is:

Both lines would be parallel and congruent

The translation is given as:

[tex]\mathbf{(x,y) \to (x + 1, y - 4)}[/tex]

Translation is a rigid transformation.

This means that, the image and the pre-image would have the same measure.

So, when a line is drawn from A to A' and B to B'

  • The lines would be parallel
  • The lines would be congruent

Assume the coordinates of A and B are:

[tex]\mathbf{A = (2,3) }[/tex]

[tex]\mathbf{B = (-4,6) }[/tex]

Apply transformation

[tex]\mathbf{A' = (2 + 1, 3 - 4) = (3,-1)}[/tex]

[tex]\mathbf{'B = (-4 + 1, 6 - 4) = (-3,2)}[/tex]

The distance of lines AA' and BB' is calculated using:

[tex]\mathbf{d = \sqrt{(x_2 -x_2)^2 + (y_2 - y_1)^2 }}[/tex]

So, we have:

[tex]\mathbf{AA' = \sqrt{(2 -3)^2 + (3 - -1)^2 = \sqrt{17}}}[/tex]

[tex]\mathbf{BB' = \sqrt{(-4 --3)^2 + (6 -2)^2 = \sqrt{17}}}[/tex]

Notice that:

[tex]\mathbf{BB' = AA' = \sqrt{17}}}[/tex]

Because translation is a rigid transformation, then lines AA' and BB' would also be congruent
