__Constructing a Right Triangle__
Video Version
 * 1) Open Sketchpad
 * 2) Draw a Segment
 * 3) Select the //Segment// and //ONE Endpoint//
 * 4) Go to //Construct -> Perpendicular Line//
 * 5) Put a //Point// on the perpendicular line
 * 6) Highlight ONLY the perpendicular line. Go to //Display -> Hide// //Perpendicular Line//
 * 7) Use the //Segment Tool// to create the two missing sides

__Quadrilateral Activity__
We are now going to work on a project that I give my students to complete by the end of the quadrilaterals unit in Geometry. File given to students: [|Quadrilaterals in Sketchpad Project.doc] //**Your instructions:**// Get in groups of 2
 * 1) Using Sketchpad, you must create 4 “dynamic sketches”. These are: parallelogram, rectangle, rhombus, and square. What does this mean?
 * Your construction must always hold the properties of the shape created. For example, if I construct a parallelogram, opposite sides are always parallel. Also, I can manipulate the side lengths and angles (if applicable) by dragging the shape's vertices and/or sides.
 * Hint: The "Construct" and "Transform" tabs will be helpful with different quadrilaterals!
 * 1) Put all 4 sketches in one file, but on different pages. How do you do that?
 * //File// -> //Document options// -> //Add page// -> //Blank Page//
 * Name each page by the quadrilateral you are creating
 * There are tabs on the bottom left corner that help you go from one page to the other.
 * In document options, also name each page by the shape you are constructing
 * 1) After you have created your dynamic shape, write specifically how you created that shape.
 * 2) You will be sharing with another group in 30 minutes!
 * 3) Check with me before uploading your file to this page.
