Final answer:
The shape of a track, like a running track with two semicircles at the end and lines connecting them, is called an oval or an ellipse. It is a type of conic section defined by two foci and constant distance sums. The straight sections are the tangent lines, and the semicircular sections are the arcs.
Step-by-step explanation:
The shape of a track, like a running track with two semicircles at the end and lines connecting them, is called an oval or an ellipse. It is a type of conic section that is defined by two foci and the sum of the distances from any point on the shape to the two foci is constant.
The straight sections of the track are called the tangent lines, and the semicircular sections are called the arcs. Together, they form the overall shape of the track.
