Perpendicular and Parallel Lines, Quadrilaterals worksheets for Grade 4 (Elementary School)

What this unit covers

Attention turns to the relationship between two straight lines, beginning with Finding Perpendicular Lines and Finding Parallel Lines. After parallel lines and angles and The Width Between Parallel Lines, trapezoids, parallelograms and rhombuses are picked out by label, and the properties of diagonals follow in one continuous thread.

Trying to tell a parallelogram from a rhombus by equal side lengths alone leads to mixing the two up, and this is also where answers that refuse to count a square as a rhombus come from. With diagonals the two properties get swapped: a rectangle has diagonals of equal length, while a rhombus has diagonals that cross at right angles.
