About Geometry Worksheet Assignment 5.13:     

 

Assignment 5.13 is an introduction to writing proofs for congruent triangles that include basic definitions and theorems using flow charts.

 

Prerequisite Skills:  Complete and write flow chart proofs (Assignment 5.11).  Identify conditions for triangle congruence (SSS, SAS, ASA, AAS, HL) (Assignment 5.5).  

 

Definitions:  Definition of Isosceles Triangle: An isosceles triangle is a triangle that has two congruent sides.

                           Definition of Midpoint: A midpoint of a line segment is a point that divides the line segment into two congruent line segments.

                           Definition of Angle Bisector: The bisector of an anglet divides the angle into two congruent angles.

 

Theorem:      Perpendicular Lines Theorem: Perpendicular Lines are lines that intersect at right angles.  Right angles are congruent.
