Question

question 9 of 10

although the locus of points idea can be used to define a straight line and circle, more complex shapes such as parabolas must be defined a different way.

a. true
b. false

Explanation:

Analyze the definition of a parabola

A parabola is defined geometrically as the locus of points in a plane that are equidistant from a fixed point (the focus) and a fixed straight line (the directrix).

Evaluate the statement

Since a parabola is indeed defined using the locus of points concept, the statement claiming that parabolas "must be defined a different way" is false.

Answer:

• A. True
• B. False (Correct answer)
