4 Questions
Explore the GeoGebra applet below before responding to the items that follow.

Exploration: What is the relationship between the endpoints of the four congruent brown segments and the isosceles trapezoid? How do you know?

Exploration: What type of quadrilateral is formed by the brown segments? Be as specific as possible.

Extension: Reset the applet and run it once more. Are your results the same? Do you think the relationship applies to all isosceles trapezoids? Explain.

Extension: Make a conjecture based on your findings in this activity.
