Exploring kite properties

Exploring Kite Properties

Exploring Kite Properties (Suggested Grades 4 - 9)
In this activity, you will explore the properties of a kite, and by dragging, particularly look at its sides, angles, diagonals, and circle properties. If not already done, it is recommended to first complete the following activity: Visually Introducing & Classifying a Kite before continuing with the one below.

Explore
1) Explore the properties of a kite by dragging vertices A, B, C, or D. (Click on the buttons to display relevant measurements).
2) What do you notice about its sides, angles, diagonals, symmetry? Does it have a circumcircle or incircle?

Conjecturing & Checking
3) Write down your conjectures in relation to your observations in 1).
4) Then check your conjectures by completing this Kite Properties Quiz which will open in a new browser window. Continue until you get a % score and you are told you've completed the exercise. If you do not get 100%, repeat your dynamic exploration in 1) above.

Logically Explaining
5) Explain (prove) using the symmetry of the kite why your conjectures in 2) to 4) are true.
6) After writing your explanations down, check and compare them with those in this exercise Kite Properties Explanations.

Notes
a) The intention of the suggested dynamic activities above is not to replace traditional geometric manipulatives such as cardboard, paper, geoboard or plastic representations of various quadrilaterals, and activities like folding & measuring by hand, but rather to supplement and compliment those hands-on concrete activities.
b) This is a suggested activity on Level 2 (Analysis of properties) of the Van Hiele theory of learning geometry. For an activity for a kite on the previous Van Hiele level of learning (Level 1), go to: Visually Introducing & Classifying a Kite.
c) For a transitional activity towards the next Van Hiele level of learning (Level 3: Constructing a kite), go to: Free construction of a kite (not yet converted to WSP).
d) Ideally, in the activity at the top, if time allows, learners & students should measure sides, angles, etc. themselves. To do so yourself, click on the 'Link to No Measurements' button to navigate to a new sketch & use the tools on the left to measure sides, angles, etc.
