Based on your questions, I can help you identify the terms you might be looking for regarding the triangles, slope, and relationship type. Here’s how to fill in the blanks:
a. Triangles ABC and CDE are called similar triangles.
b. The slope of the line AE can be written as 3/4 (assuming the rise/run calculation gives you these values).
c. This is a proportional relationship (assuming the triangles have proportional sides).
If you need more specific details about the graph or other elements, please provide additional context or description.
