==== Procedure ====
==== Procedure ====
# The teacher can use the Geogebra file to introduce properties of the quadrilateral- Rhombus.
# The slider can be used to vary the measurement of side and angle of the rhombus.
# Bring student's attention to measurements of sides, angles and diagonals.
===== Development questions =====
# Identify the type of polygon based on the number of sides.
# How are the sides of the quadrilateral related? Identify the parallel lines.
# What are the measurements of the sides? How are they related?
# What are the measurements of interior angles of the quadrilateral? How are they related?
# Identify the diagonals of the quadrilateral.
# What is the angle measurement at the intersection of the diagonals?
# Does the intersection point of the diagonals divide the diagonals equally?
# Does the diagonals bisect the interior angles of the rhombus?
# What common properties can you find with quadrilaterals rhombus and parallelogram?
# What is the difference between quadrilaterals rhombus and square?
=== Evaluation at the end of the Activity ===
=== Evaluation at the end of the Activity ===
# Give the properties of the quadrilateral rhombus.
# Observe the triangles formed by the two diagonals of the rhombus. How are they related?
# Can a rhombus have unequal sides?
