Proportional Relationships and Slope

A three-tiered cake with the diameter of the top tier measuring 6 inches, the diameter of the middle tier measuring 8 inches and the diameter of the bottom tier measuring 10 inches.

In the video, Ms. Shafer emphasizes the importance of having the cakes follow an appropriate pattern of measurements.

A three-tiered cake with the height of the top tier measuring 6 inches, the height of the middle tier measuring 6 inches and the height of the bottom tier measuring 6 inches. A one- inch distance is labeled on the surface of the middle and bottom layers to show that each layer is 2 inches larger in diameter than the one on top of it. Lines are drawn at these measurements to show two triangles formed by the tiers.

Look at these measurements from a side view. Can you spot the triangles?
