Process (How to do the activity)

 * 1) Show the geogebra file.
 * 2) Move points, the vertices of the quadrilateral and let the students observe the sum of opposite interior angles.

Developmental Questions (What discussion questions)

 * 1) What two figures do you see in the figure ?
 * 2) Name the vertices of the quadrilateral.
 * 3) Where are all the 4 vertices situated ?
 * 4) Name the opposite interior angles of the quadrilateral.
 * 5) What do you observe about them.

Evaluation (Questions for assessment of the child)

 * 1) Compare the cyclic quadrilateral to circumcircle.

Question Corner

 * 1) Name this special quadrilateral.
