A Quadrilateral. All rhombuses fall under the category of quadrilaterals, a flat shape with four sides. What makes rhombuses special is that all four of the sides are all the same length. If you are given the length of just one side of a rhombus, then you also know the measurement of all the other sides because of this property. This is the identifying property of a rhombus.
Once you start the Reflector app, you will have to use a separate screencast utility, like we mentioned before, for your Mac or Windows PC for the actual recording part. We recommend CamStudio (open source and good) for Windows and Jing (free) for Mac.
Part of the Multimedia and graphics glossary: A screencast is a digital video recording that captures actions taking place on a computer desktop. Screencasts, which often contain voice-over narration, are useful for demonstrating how to use specific operating systems, software applications or website features. Screencast production requires some kind of video-capture software and a microphone. The software, which can be a desktop client or web-based service, captures and synchronizes the video and audio files and compresses the completed movie into a format that can be shared.
