Question

When using the Ellipse - Foci Method, how are the focal points (F1 and F2) located?
Options
A By bisecting the major axis AB.
B By drawing an arc from point C or D (ends of the minor axis) with a radius equal to half of the major axis (OA) to cut the major axis.
Correct Answer
C By drawing an arc from point A or B (ends of the major axis) with a radius equal to half of the minor axis (OC) to cut the minor axis.
D By dividing the major axis into a convenient number of equal parts.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 7, Step 2 of 'ELLIPSE- Foci Method' states: 'Find the focal points by drawing an arc from point C or D with radius OA (½ of major axis) to cut the major axis at F1 and F2.'

Hint

Review Step 2 of the 'ELLIPSE- Foci Method' on page 7.
