Quadrilateral Properties: Rhombus
Before you start
What is a rhombus? Be precise with your definition.
Move points B and C and observe what happens to the rhombus.
Rhombus
In a quadrilateral, opposite sides are those across from each other, not touching or sharing any vertices. For example, AC and BE are opposite sides in the rhombus here.
Is there a relationship between opposite sides of the rhombus? If so, what is the relationship?
Consecutive sides are those right next to each other (touching) in a polygon. For example, AC and CE are consecutive sides in this rhombus.
Is there a relationship between consecutive sides of the rhombus? If so what is the relationship?
Now consider the angles in the diagram. Use the checkboxes as needed.
What is the relationship between opposite angles of the rhombus?
What is the relationship between consecutive angles of the rhombus?
Now let's add the diagonals to the rhombus. Diagonals are segments that connect one vertex to another non-consecutive vertex.
