Try to form a triangle with the 3 segments shown by dragging the endpoint of one of the segments onto the endpoint of another segment. If this doesn't work, change the lengths of the sides by using the sliders and change the angle measurement by moving the red endpoints of the lines. Try to create a triangle. If you created a triangle the triangle will become solid.
Can a triangle be created with any 3 measurements?
Find the sum of the lengths of two of the sides and compare it to the remaining side. What do you notice?[br]
What has to be true about the third side in relation to the other two?
