Down: 1) a prism is a three-dimensional figure with two parallel and congruent polygonal faces, called bases. a prism is named for the shape of its base.2) an edge is a segment formed by the intersection of two faces of a three-dimensional figure.3) circumference is the distance around a circle. You calculate the circumference of a circle by multiplying the diameter by pi or 3.144) CENTER OF A CIRCLE-a circle is named by its center CENTER OF A SPHERE- where all points in space lead directly to. page 438 9) in a right triangle, the hypotenuse is the longest side which is opposite of the right angle.10) a perfect square is a number that is the square of an integer.14) finding the square root of a number is the inverse of squaring number 15) the legs of a right triangle are the two shorter sides of the triangle that form the right angle.17) a face is a flat surface of a surface of a three-dimensional figure that is shaped like a polygon. Across: 1) pi is the ratio of the circumference C of any circle to its diameter d. pi equals 3.145) a cubic unit is a cube whose edges are one unit long.6) a sphere is the set of all points in space that are the same distance from the center point. 7) NOT ON TEST. the surface area of a prism is the sum of the areas of its faces. 8) height of 3D figure- cylinders and prism on page 437-438 height of 2D figure-paralleograms,triangles,trapezoid on page 407,408,41311) a pyramid is a three-dimensional figure with triangular faces that meet at a vertex and a base is a polygon. a pyramid is named for the shape of its base.12) in any right triangle, the sum of the squares of the lengths (a and b) is equal to the square of the length of the hypotenuse. (a2+b2=c2)13) THESE ARE THE VOCAB WORDS WE NEED TO KNOW FOR OUR TEST16) a cylinder is a three-dimensional figure with two congruent parallel bases that are circles. 18) the area of a figure is the number of square units it encloses19) when a number is written in exponential form, the number that is used as a factor is the base. THE BOTTOM LINE SEGMENT OF A OBJECT20) a cone is a three-dimensional figure with one circular base and one vertex.21) VERTEX OF A POLYGON-the vertex of a polygon is any point where the two sides of a polygon meet 22) a cube is a rectangular prism whose faces are all squares 23) the volume of a three-dimensional figure is the number of cubic units needed to fill the space inside the figure.
