Tutorial+1+-+Point,+Segment,+and+Intersection+Tools

 **Objective:** To construct a triangle and find its centroid. **Tools:** Move, New Point, Segment between Two Points, Midpoint or Center, Intersect Two Objects  Use the same tool to construct segments //AC// and //BC//. ||
 * **No** || **Tool** || **Instruction** ||
 * 1 || [[image:gip-manila/point.png]] || Select the //**New Point**// tool and click three different locations on the //Graphics view//. ||
 * 2 || [[image:gip-manila/segment.png]] || To construct side //AB//, select the //**Segment between Two Points**// tool click point //A//, and then click point //B//.
 * 3 || [[image:move.png]] || Select the //**Move**// tool and drag the points. What do you observe? ||
 * 4 || [[image:gip-manila/midpoint.png]] || To construct the midpoint of //AB//, select the //**Midpoint or Center**// tool, click point //A//, and then click point //B//. Now, get the midpoints of //AC// and //BC//. After this step, your drawing should look like the following figure.

||
 * 5 || [[image:gip-manila/segment.png]] || To construct the medians, use the Segment between Two Points tool to construct segments //AF//, //BE//, and //CD//, the medians of the triangle. ||
 * 6 || [[image:gip-manila/intersect.png]] || To intersect the medians, select the //**Midpoint or Center**// tool, and then click any of the two medians. ||

 * Move points //A//, //B//, and //C//. What do you observe about the medians?
 * What conjecture can you make about the medians of a triangle?
 * Move the points and the segments on the figure. Which objects can/can't be moved? Why?
