Complete the following tasks: [br][br]1) Use the RAY [icon]/images/ggb/toolbar/mode_ray.png[/icon] tool to construct a ray with endpoint [i]A[/i] that passes through [i]B[/i]. [br][br]2) From this ray, construct another ray using the same vertex point [i]A[/i] that passes through [i]C[/i]. [br][br]3) Next measure the angle you created using the ANGLE tool. [br][br]4) Now we will create an angle (with vertex = endpoint of this ray) whose measure is the same as angle you created. To do this first create another RAY [icon]https://www.geogebra.org/images/ggb/toolbar/mode_ray.png[/icon]. Then select the ANGLE WITH GIVEN SIZE [icon]https://www.geogebra.org/images/ggb/toolbar/mode_anglefixed.png[/icon] tool. Select in order the point on the ray, then the vertex, and then enter the value for the angle measure. [br][br][color=#0000ff]Further directions appear below the applet. [/color]
7) What is the sum of the three angles inside the triangle?
