Properties of Ellipses Quizizz

Standard Form of a Ellipse

• (x-h)² + (y-k)² = r²

• (x-h)²/a² + (y-k)²/b² = 1

• (x-h)²/a² - (y-k)²/b² = 1

• x = a(y-h)² + k

The major axis is:

• The shorter axis of an ellipse
• The longer axis of an ellipse
• The closest point closest to the Sun
• The farthest point closest to the Sun

What is the center of the ellipse?

• (0, 0)
• (1, 5)
• (1, 0)
• (0, 1)
