Isometric Geometry
Corner views of three-dimensional objects on two-dimensional paper.
Cross section
The intersection of a solid and a plane.
Lateral face
In a solid figure, faces that are not bases. \n
Lateral edge
The intersection of two lateral faces.
Base edge
The intersection of a lateral face and a base.
Altitude
A perpendicular segment that joins the planes of the bases.
Height
The length of the altitude of a solid figure.
Lateral area
The sum of the areas of a figure not including the bases.
Axis
The segment with endpoints that are the centers of the bases of a cylinder
Composite solid
A three-dimensional figure that is composed of simpler figures
Regular pyramid
A pyramid with a base that is a regular polygon.
Slant height
The height of a lateral side of a pyramid or cone.
Right cone
A cone with an axis that is also an altitude.
Oblique cone
A cone that is not a right cone.
Great circle
A circle formed when a plane intersects a sphere with its center at the center of the sphere.
Pole
The endpoints of a diameter of a great circle.
Hemisphere
One of the two congruent parts into which a great circle separates a sphere.
Euclidean geometry
A geometrical system in which a plane is a flat surface made up of points that extend infinitely in \n all directions.
Spherical geometry
The branch of geometry that deals with a system of points, great circles (lines), and spheres \n (planes).
Non euclidean geometry
The study of geometrical systems that are not in accordance with the Parallel Postulate of \n Euclidean geometry.
Similar solids
(Blank) have exactly the same shape but not necessarily the same size.
Congruent solids
(Blank) have exactly the same shape and the same size.
