    circle geometry

    Hi All,

    I am a doctoral student working on my first year project. I am recreating an experiment by Tarmizi and Sweller(1988) which highlights the benefits of using worked examples.

    In their study, they teach 9th graders two theorems related to circle geometry. The first theorem states that angles in the same segment of a circle are equal. The second theorem states that opposite angles of a cyclic quadrilateral are supplementary.

    Can some tell me where I can get examples of these theorems? I also need to provide the participants in my study with examples of the two theorems being applied. I need approximately 20 practice problems.

    Can some please tell me where I can go to find the examples/practice sets?

    Thanks! :-)
