===Process (How to do the activity)===
#The teacher can do this activity after introducing the concept and properties of cyclic quadrilateral.
#She can project the file and let students watch it carefully.
#After watching discuss the steps of construction and the purpose of each step so that the students can appreciate the sequence of construction steps.
#Then ask the students to actually construct a cyclic quadrilateral for the given measures.
*Developmental Questions:
#What is a cyclic quadrilateral ? Why is it called so ?
#Name the measuring parameters of it ?
#What measures are given for its construction ?
#Explain the steps involved in determing the radius of the required circle ?
#What do the measures of the arcs specify ?
*Evaluation:
#Were the students able to justify the sequence of steps involved ?
*Question Corner:
#Can you draw a circle first and then the quadrilateral ? Why not so ?
