This presentation is dedicated to a parallelogram. It starts with the definition which is followed by a clear and easy explanation of the six properties of a parallelogram. Each property is consequently proven. Succesfully used this presentation in my own practice, therefore with confidence recommend it as an easy way to support your explanation on the topic.
