Identifying an Ellipse from its Equation
When analyzing a general conic section equation, the graph represents an ellipse if the equation contains both and terms that share the same sign but have different coefficients. For example, the equation represents an ellipse because the squared terms ( and ) are both positive but have different numerical coefficients.

A facilities management team is reviewing the blueprints for a new elliptical boardroom table. To ensure the design meets the geometric specifications of an ellipse, match the following architectural terms to their mathematical definitions based on the concept of an ellipse.
An urban planner is designing an elliptical fountain for a city plaza. They need to identify the longest line segment that passes through the center of the fountain and connects the two vertices on its boundary. According to the geometric definition of an ellipse, what is the mathematical term for this line segment?
A specialized contractor is constructing an elliptical 'whispering gallery' for a science museum. This architectural feature relies on the geometric definition of an ellipse, which states that for any point on the curved wall, the ____ of the distances to the two fixed internal points (foci) is always constant.
Identifying the Minor Axis in Architectural Drafting
A carpentry apprentice is drafting an elliptical conference table for a corporate client. To draw the precise shape onto a sheet of wood, they secure two push-pins to the surface and trace the curve by keeping a loop of string taut around both pins and a pencil. According to the geometric definition of an ellipse, the locations of these two fixed pins represent the foci of the ellipse.
