Question

For the ELLIPSE - Foci Method, how are the focal points (F₁ and F₂) located?
Options
A By bisecting the major and minor axes.
B By drawing an arc from point C or D with radius equal to 1/2 of the minor axis to cut the major axis.
C By drawing an arc from point C or D with radius equal to 1/2 of the major axis to cut the major axis.
Correct Answer
D By measuring 1/3 of the major axis from each end.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 7, 'STEPS 2' of the Ellipse - Foci Method states: 'Find the focal points by drawing an arc from point C or D with radius OA (1/2 of major axis) to cut the major axis at F₁ and F₂.'
