1. Select the SEGMENT WITH GIVEN LENGTH [icon]/images/ggb/toolbar/mode_segmentfixed.png[/icon] tool, and enter a length of 4.[br]2. Select the LINE [icon]/images/ggb/toolbar/mode_join.png[/icon] tool. Click on point A and then somewhere above or below segment AB.[br]3. Select the ANGLE [icon]/images/ggb/toolbar/mode_angle.png[/icon] tool. Click points B, A, and C to measure angle A. If the measurement is over 180°, undo and click on them in reverse order.[br]4. Select the MOVE [icon]/images/ggb/toolbar/mode_move.png[/icon] tool, and move point C until angle BAC has a measure of 37°.[br]5. Repeat steps 2–4 to create angle DBA with a measure of 73°.[br]6. The place where the lines meet is the third vertex of your triangle. Use the INTERSECT [icon]https://www.geogebra.org/images/ggb/toolbar/mode_intersect.png[/icon] tool to mark it as point E.[br]7. Select the DISTANCE OR LENGTH [icon]/images/ggb/toolbar/mode_distance.png[/icon] tool, and then click on points A and E to measure the distance between them. Do the same for points E and B.[br]8. Answer the questions below the applet by constructing each triangle describe below.
Construct a triangle with a 37° angle and a 73° angle connected by a side of length 4. What are the lengths of the other two sides?
Construct a triangle with a 12° angle and a 53° angle connected by a side of length 5. What are the lengths of the other two sides?
Construct a triangle with a 103° angle and a 28° angle, with a side of length 8 between the 28° angle and third angle. What are the lengths of the other two sides?
