I don't understand how to do this exactly can someone help?
List two sets of possible side lengths for two triangles. For example, you could list the side lengths 3, 4, and 5. One of your sets of side lengths should be able to form a triangle and one of your sets of side lengths should not be able to form a triangle.
Give the coordinates of three vertices that could be connected to form a right triangle on a coordinate plane. For example, the points left parenthesis negative 4 comma 2 right parenthesis, left parenthesis 4 comma 2 right parenthesis, left parenthesis 4 comma 6 right parenthesis and could be plotted and connected to form a right triangle.
