link to chapter 9 gaja118 Chapter - __Blue Box__: PG: 430- surface area and volume formulas for right rectangular prisms: V=L*W*H SA={L*W*2}+{L*H*2}+{W*H*2}
 * 7.1**

- __Bold Words__: **Surface area**-the sum of the areas of all faces of a prism
 * Volume**- one face area of a prism multiplied by length

- __Blue Box’s__: PG: 438- surfaced area of a right prism: SA=L+2B or SA=HP+2B PG: 440- Cavalieri’s principle, if two solids have equal heights and the cross section formed by every plane parallel to the basses of both solids have equal areas, then the two solids have equal volume PG: 440- volume of a prism, base*height
 * 7.2**

- __Bold Words__:
 * Altitude**- similar to the height of the prism
 * Height**- length of the altitude

7.3 - __Blue Box__: PG: 446 surface area of a regular pyramid SA=L+B

- __Bold Words__: Regular pyramid- Slant height- - Pictures:
 * Pyramid**- polyhedron consisting of a base
 * Lateral faces**- triangles that share a single vertex, called the Vertex of the pyramid
 * Base edge**- each lateral face has one edge in common in he base
 * Lateral edge**- the intersection of two lateral faces
 * Altitude**-height of a pyramid perpendicular to the base
 * Height**- the length of the altitude

8.1 - __Blue Box__: - __Bold Words__:
 * Dilation:** transformation that is not rigid


 * Scale Factor:** dilation of a point in a coordinate plane can be found by multiplying the x and y coordinates of a point by the same number n D{x,y}={nx,ny} n is called the scale factor
 * Center** **of** **Dilation****:** each point and image lie on a strait line that passes through a point called center of dilation
 * Contraction:** if the size of a figure is reduced by dilation
 * Expansion:** if the size of a figure is enlarged by dilation

8.2 __Blue Box__: PG: 507- definition of similar figures [see similar in bold words] PG: 508- polygon similarity postulate: two polygons are similar if and only if there is a way of setting up a correspondence between their sides and angles __Bold Words__:
 * Similar:** two figures are congruent if and only if one is congruent to the image of the other by dilation
