# Students constructing materials, the geometry box.
# white papers.
*Prerequisites/Instructions, if any
*Prerequisites/Instructions, if any

*Website interactives/ links/ / Geogebra Applets
*Multimedia resources : Laptop
*Process/ Developmental Questions
*Website interactives/ links/ / Geogebra Applets: For step by step illustration of cyclic quadrilateral construction please refer to the website: http://www.matrusrieppower.net/Constructionoftriangleandcyclicquadrilateral.html.
*Evaluation
*Process:
*Question Corner
# The teacher can so 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 ?
# Why was the 60 degree angle constructed ?
# 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 ?
