Undefined terms: terms that cannot be defined by using other figures.
Collinear: Points that lie on same line Coplanar: Points that lie on same plane collinear Ex. 1a: points K, L, M are ____________ Ex. 1b: points N, K, L are _______________ noncollinear Ex. 2: Use the diagram to name two planes plane R, plane ABC, plane ACB, plane BAC, plane BCA, plane CAB, plane CBA
Postulates or axioms: statement that is accepted as true without proof. Ex. 3: Name a plane that contains three noncollinear points. plane GHF, plane GFH, plane HGF, plane HFG, plane FGH, or plane FHG
Intersection: Set of all points that two or more figures have in common. Use DASHED line to show the hidden parts of any figure you are drawing, will indicate the part of figure that is unseen. Ex. 4a: Sketch a figure that shows a line intersecting a plane, but does not lie on the plane.
Ex. 4b: Sketch a figure that shows two planes intersecting in one line. Pg. 9 _______________________________________________
