GET 102 GEOMETRIC CONSTRUCTION: CONIC SECTIONS Objective Question

Question

In the ELLIPSE - Concentric Circle Method, what are the radii used for constructing the two concentric circles?
Options
A Radii equal to the major axis and minor axis.
B Radii equal to the full major diameter and full minor diameter.
C Radii equal to 1/2 of the major axis and 1/2 of the minor axis.
Correct Answer
D Radii equal to the focal length and the minor axis.
Correct Answer

Option C is the correct answer.

Detailed Explanation

According to 'STEPS 1' on page 6 for the Ellipse - Concentric Circle Method, the two concentric circles are constructed 'with radii equal to 1/2 of major and 1/2 of minor axes'.

Hint

Refer to the first step of the Concentric Circle Method for drawing an ellipse.
