</span>   <span><span>Dilation - of a polygon</span> A transformation in which a polygon is enlarged or reduced by a given factor around a given center point. Try this Adjust the slider on the right to change the scale factor. Drag the center point O. Dilation is where the polygon grows or shrinks but keeps the same overall shape. It's a little like zooming in or out on a camera. In the figure above, the polygon is a rectangle ABCD. As you adjust the slider on the right, the transformed rectangle A'B'C'D gets bigger and smaller, but remains the same shape</span></span>

To dilate a shape means ur either going to make it larger or ur going to make it smaller. U will do this by multiplying every side of ur shape by a certain number.

if u r dilating it from a smaller shape to a larger shape, u would multiply it by a whole number.

if u r dilating it from a larger shape to a smaller shape, they u would multiply it by a fraction less then 1.

example :
u have a larger shape with one side measuring 6 inches...and u have another one (the smaller one) with the side that is 2 inches. To find the scale factor...it basically is set up like this : 6 * ? = 2....6x = 2....x = 2/6 which reduces to 1/3....meaning for every side of the big shape, multiply it by 2/3 to get the size of the small shape...notice how from going bigger to smaller, u r multiplying by a fraction to get the sizes of the smaller shape.

now if u have a smaller shape with a side measuring 2 inches...and a larger shape with a side measuring 6 inches (going from smaller to larger), u would multiply everything on the small shape by 3 because 2 * 3 = 6. So the scale factor would be 3. so going from smaller to larger, u r multiplying by a whole number

Quadrilateral ABCD is the result of a translation of quadrilateral EFGH. Segment EF is parallel to segment HG in the pre-image.
dimulka [17.4K]
Translations of figures preserve the lengths and angles of the original figures, then all the segments of the image figure are parallel to correspondant segments of the original figure.

Then you can state that the same relation between any two sides of the original figure is what you will have for the image.

AB is parallel to HE

AD is parallel to HG

DC is parallel to GF

BC is parallel to EF


Then is EF is parallel to HG in the pre-image the correspondant segments in the image are parallel too, i.e. BC is parallel to AD in the image.

Which is the best first step and explanation for solving this system of equations?
Volgvan

Answer:

x=-4/9, y=10/3. (-4/9, 10/3).

Step-by-step explanation:

3x+4y=12

3x=2y-8

--------------

2y-8+4y=12

6y-8=12

6y=12+8

6y=20

y=20/6

simplify,

y=10/3

3x=2(10/3)-8

3x=20/3-8

3x=20/3-24/3

3x=-4/3

x=(-4/3)/3

x=(-4/3)(1/3)=-4/9

x=-4/9, y=10/3. (-4/9, 10/3).
