1
Warm Up Graph each inequality. 1. x ≥ 3 2. 2 ≤ x ≤ 6 3. x 0 -2024 0246 01
2
Undefined terms:terms that cannot be defined by using other figures.
3
Collinear:Points that lie on same line Coplanar:Points that lie on same plane Ex. 2: Use the diagram to name two planes plane R, plane ABC, plane ACB, plane BAC, plane BCA, plane CAB, plane CBA Ex. 1a: points K, L, M are ____________ Ex. 1b: points N, K, L are _______________ collinear noncollinear
5
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
6
Intersection:Set of all points that two or more figures have in common. Ex. 4a: Sketch a figure that shows a line intersecting a plane, but does not lie on the plane. Use DASHED line to show the hidden parts of any figure you are drawing, will indicate the part of figure that is unseen.
7
Ex. 4b: Sketch a figure that shows two planes intersecting in one line. Pg. 9 _______________________________________________
