10. Looking at the graph:

(3 points)
a. Triangles ABC and CDE are called **answer** triangles.

b. The slope of the line AE can be written as **answer**

c. This is a **Answer** relationship.

a. Triangles ABC and CDE are called similar triangles.

b. The slope of the line AE can be written as (change in y-coordinate)/(change in x-coordinate).
c. This is a linear relationship.

a. Triangles ABC and CDE are called congruent triangles.

b. The slope of the line AE can be written as (change in y / change in x).

c. This is a linear relationship.

To answer these questions, we need to analyze the given graph.

a. Triangles ABC and CDE are called **similar** triangles. Similar triangles are triangles that have the same shape but differ in size. To identify similar triangles, we look for corresponding angles that are equal in measure. In this case, triangles ABC and CDE have corresponding angles that are equal in measure, hence they are similar triangles.

b. The slope of the line AE can be written as **rise over run**. To find the slope of a line, we need to determine the change in the y-coordinates (rise) divided by the change in the x-coordinates (run) between any two points on the line. In this case, choose two points on the line AE and calculate the rise over run to find the slope.

c. In order to determine the relationship provided in the question, we need more context or specific information about the graph. Please provide additional details or refer to the graph for further analysis.
