poems

I think poems are more interesting then prose because in a poem they make a story short with a lot of details and they make the story rhyme so it could sound more interesting .

Transformations-Dilations

A dilated figure changes it's shapes size.When you zoom in on a photo you are making things bigger .zooming relates to dilation by making some thing bigger because in dilation you make something bigger or smaller . If a figure undergoes a dilation with a scale factor of 1.5 the figure does get bigger because the scale factor is greater than one.It is not the same if the scale factor is 0.5 because o.5 is less than 1 and if a scale factor is less than one the the dilation's will be smaller. A dilation differs from a translation because in a translation you change the location and in a dilation you change the size.

Transformations-Translations

When looking at two figures I know which shape has the transformation by looking at the shapes plotted points for example A,B,C,D are the plotted points then there will be another set of points like A',B',C',D', the plotted points with the comma are the plotted points with the transformation.Words I could use to describe a translation is transform and change .The new transformed points are called prime points.A new translated figure will never change shape because a translation is changing a shapes location.You can translate a figure whit out a coordinate by using the plotted points to help you change the shape for example if you have a triangle and the plotted points are (3,7) - (2,4) - (5,5) and in the problem it says to move the figure 2 units to the left or right all you do is add 2 units to the x-axis and then your figure will change to (5,7) - (4,4) - (7,5).
