The most fundamental concepts in geometry do not have precise definitions but, we understand their meanings intuitively. We say these concepts are undefined. What are the undefined terms? Point: : Geometry Leeson: Undefined Terms, Lines, Line Segments 2 A point indicates a position or location in space. . P Point: Points are named using capital letters and/or coordinates. Line: : Geometry Leeson: Undefined Terms, Lines, Line Segments 3 A line is an infinite set of adjacent points. Line: Plane: : Geometry Leeson: Undefined Terms, Lines, Line Segments 4 Plane: A plane is a set of points that forms a completely flat surface. Def: Collinear Points: : Geometry Leeson: Undefined Terms, Lines, Line Segments 5 Def: Collinear Points: A collinear set of points is a set of points all of which lie on the same straight line. Points A, B, C and D are collinear. Points A, E and C are not collinear. Def: Line Segment: : Geometry Leeson: Undefined Terms, Lines, Line Segments 6 Def: Line Segment: A line segment is the set of two points on a line called endpoints, and all points on the line between the endpoints. Measure of Line Segments: : Geometry Leeson: Undefined Terms, Lines, Line Segments 7 Measure of Line Segments: The measure of a line segment is the length of the line segment. Ans. BC=36 cm Def: Congruent Line Segments: : Geometry Leeson: Undefined Terms, Lines, Line Segments 8 Def: Congruent Line Segments: Congruent line segments are segments that are equal in measure. Then AB = CD Ans. CD = 29, AB = 29 Def: Midpoint : Geometry Leeson: Undefined Terms, Lines, Line Segments 9 Def: Midpoint The midpoint of a line segment divides the line segment into two congruent segments. Def: Line Bisector : Geometry Leeson: Undefined Terms, Lines, Line Segments 10 Def: Line Bisector The bisector of a line segment is a line that intersects the line segment at its midpoint. X Addition and Subtraction of Line Segments: : Geometry Leeson: Undefined Terms, Lines, Line Segments 11 Addition and Subtraction of Line Segments: If several line segments belong to the same line, we can write addition and subtraction expressions using the names of these segments. Simple 2-Column Proof : Geometry Leeson: Undefined Terms, Lines, Line Segments 12 Simple 2-Column Proof Given Definition of Line Bisector Definition of Midpoint You do not have the permission to view this presentation.
