About Geometry Worksheet Assignment 4.23:        

 

Assignment 4.23 is an introduction to theorems about lengths of diagonals in parallelograms and isosceles trapezoids.

 

Prerequisite Skills:  Measure line segments (Assignment 1.11).  Name line segments (Assignment 1.12).   

 

Theorems:     The diagonals of a parallelogram are bisect each other.

                             The diagonals of a rectangle are congruent.

                             The diagonals of an isosceles trapezoid are congruent.
