What is the definition of a parabola for CONIC sections

The video tutorial explains the basic definition of a parabola, focusing on its U-shape and the role of the vertex and focus. It describes how the distance from the focus to any point on the parabola is equidistant to the directrix. The tutorial also touches on the properties of parabolas in conic sections, including their ability to open in different directions.

What is the basic shape of a parabola?

• A U-shape

• A square

• A triangle

• A circle

What is the most important point on a parabola?

• The vertex

• The axis

• The focus

• The directrix

How does light behave in relation to the focus of a parabola?

• It passes through the vertex

• It scatters randomly

• It deflects into the focus

• It reflects away from the focus

What is the line called that is equidistant from any point on the parabola?

• The directrix

• The tangent

• The chord

• The axis

In which directions can a parabola open?

• Only diagonally

• Up, down, left, or right

• Only left or right

• Only up or down
