Harvey makes custom countertops out of thick slabs of wood. After finishing a project for a client Harvey has a scrap piece wood that is diagramed below. These pieces of wood are very expensive, and he wants to minimize waste. He decides to make a table out of this scrap piece of wood without making any additional cuts. Harvey wants the able to have 3 legs that meet at one point on the underside of the table. Where should all three legs meet so that the table is level?

Determine which point of concurrency would be utilized and explain which properties about that point of concurrency are represented in the problem. You are then need to create a diagram or model displaying why that point of concurrency works.

Denise has two dogs that like to roam. She is tired of soaking wet dogs coming into her house, her neighbors are tired of unwelcome visitors, and she doesn’t want to worry about them getting hit by a car.
