Explain using complete sentences the difference between similarity and congruence. Be sure to include what must be true of corre

sponding sides for each and what must be true of corresponding angles for both similar and congruent figures.

In similar figures, angles or sides are proportional, but in congruence, figures are exactly the same- angles, sides, and everything.
Additionally, similar figures always have the same shape, but not always the same size. But in congruence, figures always have the same shape AND size.

So, corresponding sides for similar figures should be proportional (that is, have the same scale factor. And corresponding sides in congruent figures must be exactly the same.

Hope that helps!

Need help with Select Expansion or Contraction to correctly describe the type of dilation for each given scale factor.
ad-work [718]

To know if a dilation is an expansion ( bigger) r a contraction ( smaller) ignore the negative sign.

If the number is larger than 1, it is an expansion, if the number is smaller than 1 it is a contraction.


-4 is an expansion

2.5 is an expansion

2/3 is a contraction

-3/4 is a contraction

Surface area is taking the area of each face and adding it together. The equation is 2lw + 2hw + 2hl. So, for example, you'd take the length and the width to the find the area of the top. Multiply this by 2 to find the top AND the bottom. You need to end with 6 sides and all these together to find your surface area.

If we changed the –0.14 to a 2 in the equation, what would happen to the graph?
MatroZZZ [7]

If -0.14 is changed to 2, the graph would become a positive graph, or it would be steeper, because it has a positive slope

The equation of the graph is given as:

y = -0.14x + 3

The above equation is a linear equation, which is represented as:

y =mx + c

Where m represents the slope of the linear equation.

By comparison, we have:

m = -0.14

i.e. the slope of the equation y = -0.14x + 3 is -0.14

When -0.14 is replaced with 2, the equation becomes

y = 2x + 3

And the slope of the new equation y = 2x + 3 is

m =2

2 is greater than -0.14, and 2 is positive.

This means that the graph would become a positive graph, or it would be steeper, because it has a positive slope
