Investigation: Intersecting Chords of a Circle On completion of the investigation I had learned many new important qualities associated with the intersecting chords within a circle theorems. The three theorems studied in this investigation include: Two chords intersecting externally‚ two chords intersecting internally and the intersection of a chord and tangent. Each theorem can be used to determine different things (e.g. the tangent-chord theorem can be used to determine the approximate distance

Cartesian coordinates in three dimensions A three dimensional Cartesian coordinate system‚ with origin O and axis lines X‚ Y and Z‚ oriented as shown by the arrows. The tick marks on the axes are one length unit apart. The black dot shows the point with coordinatesX = 2‚ Y = 3‚ and Z = 4‚ or (2‚3‚4). Choosing a Cartesian coordinate system for a three-dimensional space means choosing an ordered triplet of lines (axes)‚ any two of them being perpendicular; a single unit of length for all three

Soon enough she was done and Mr. Cunningham turned towards the the circle and waved his hands. They slumped their shoulders and retreated to their cars. I stood there in shock. I couldn’t breath‚ or move

paper cones. The step we took are the following ones: Gather all necessary equipment (see ’Apparatus’ section) Cut out five identical circles. The circle is divided into 36 sections‚ which means that each section is 10 degrees. Use glue to create paper cones but dont cut out any sections‚ because that way the mass is going to change For the first circle stick three sections together and for the others‚ each time increase the number of sections sticked together by three.
