Geometric Book Tareah Meeks April 10,2013 Obj: I will create a digit product while integrating two or more technology tools.
Acute Triangle A triangle for which all interior anglesare acute.
Altitude of an Cone The distance from the apex of a cone to the base. Formally, the shortest line segment between the apex of a cone and the (possibly extended) base. Altitude also refers to the length of this segment
Base In plane geometry or solid geometry, the bottom of a figure. If the top is parallel to the bottom (as in a trapezoidor prism), both the top and bottom are called bases.
Between Point B is between points A and C if it is on the line segment connecting A and C.
Box A box shape in three dimensional figure. Formally, a polyhedron for which allfaces are rectangles.
Cone A threedimensionalfigure with a single base tapering to an apex. The base can be any simple closed curve. Often the word cone refers to a right circular cone.
Cube A regular polyhedron for which all faces are squares. Note: It is one of the five platonic solids.
Cylinder A three-dimensional geometric figure withparallel congruentbases. The bases can be shaped like any closed plane figure (not necessarily a circle) and must be oriented identically.
Double Cone A geometric figure made up of two right circular cones placed apex to apex as shown below. Typically a double cone is considered to extend infinitely far in both directions, especially when working with conic sections anddegenerate conic sections.
Kite A quadrilateral with two pairs of adjacent sidesthat arecongruent. Note that the diagonals of a kite are perpendicular.
Octagon A polygon with eight sides.
Parallel Lines Two distinctcoplanar lines that do not intersect. Note: Parallel lines have the same slope.
Pentagon A polygon with five sides.
Prism A solid withparallel congruentbases which are both polygons. The bases must be oriented identically. The lateral faces of a prism are all parallelograms or rectangles.
Pyramid A polyhedron with a polygonalbase and lateral faces that taper to an apex. A pyramid with a triangular base is called a tetrahedron.
Ray A part of a line starting at a particular point and extending infinitely in one direction.
Reflection A transformation in which a geometric figureis reflected across a line, creating a mirror image. That line is called the axis of reflection.
Similar Identical in shape, although not necessarily the same size.
Sphere A threedimensional solid consisting of all points equidistant from a given point.
Square A rectangle with all four sides of equal length. Formally, a square is a quadrilateral with four congruent sides and four congruent angles (all 90°).
