Estimated Time
40 minutes.

http://www.matrusrieppower.net/Constructionoftriangleandcyclicquadrilateral.html.
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 ?
