Step 27: Drag the new point to see how its movements compare to the ray’s control points. Why can’t you construct the midpoint of a ray? Question 6: Complete question 6 on your student worksheet: With the ray still selected, go to the Construct menu and select Point on Ray.Why do you think you can’t measure the length of a ray? Select the ray and go to the Measure menu. Question 5: Complete question 5 on your student worksheet: Question 4: Complete question 4 on your student worksheet:Ī ray with endpoint A that passes through a point B is called ray AB, and is represented as. Step 25: Use the Selection Arrow tool to drag each point to observe how it controls the ray. Label the endpoint of the ray A and the other point B. Notice that the ray extends in one direction out of your window. You have constructed what are called the "control points" of the ray. Step 23: With the Ray tool selected, click on the left hand side of the sketch (this is the endpoint of the ray), and then move the cursor (arrow) to a point on the right of the initial point to complete the sketch of the ray. The Ray tool is located in the middle of the straightedge tools it consists of an endpoint and one arrow. The Straightedge tools will appear out on the right. Press and hold down the mouse button on the Segment tool.Step 21: In the File menu, choose a New Sketch. Complete each of the following steps, remembering to stop and complete the analysis questions as they appear. By the end of this sketch you will be able to compare and contrast the properties of line segments, rays and lines. In this sketch you will also be exploring the properties of rays and lines. The Straightedge tool has three different features: segment, ray and line. Sketch 2: The purpose of this sketch is to explore the Straightedge tool as part of Geometer’s Sketchpad. After you type in the new label, select OK. You are now given the option to change the label. To change the label, use the Text Tool, and double click on the label.Geometer’s Sketchpad will automatically label these points in alphabetical order, based on the order in which the points are selected. ![]() Position the hand over a point and click to label the point. Step 2: Highlight the Selection Arrow tool, and click in a blank area in the sketch. Click again to construct a second point at another location of your choosing. Step 1: Highlight the Point tool and click in the sketch to construct a point at a location of your choosing. You will learn how to construct a midpoint, and you will examine the Animation feature of Geometer’s Sketchpad. ![]() In addition, you will learn how to label points, which will be important as we begin more complicated activities. Sketch 1: The purpose of this sketch is to learn how to use the Point tool and Segment tool of Geometer’s Sketchpad.
