Answer:
The Slope of both the lines is the same.
Step-by-step explanation:
Given two co-ordinates (x1, y1) and (x2, y2), the slope of a line can be found using the formula:
For the diagonal line of the first triangle, the coordinates are (0, 0) and (2, 1)
For the diagonal line of the large triangle, the coordinates are (2, 1) and (6, 3)
