Ellipse (Part 1)

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

What are the vertices of the ellipse?

• (0, 0)
• (7, 1) and (-1, 1)
• (3, -5) and (3, 7)
• (3, 1)

What is the center of the ellipse?

• (0, 0)
• (1, 5)
• (1, 0)
• (0, 1)

What equation is used to find the foci points on an ellipse?

• c² = a² + b²
• c² = a² - b²
• 1/4d
• (x-h)² + (y-k)² = r²

An ellipse is:

• A big oval shape
• The longer axis
• The closest point closest to the Sun
• The farthest point closest to the Sun

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

The minor 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

The line through the center of your ellipse that is perpendicular to your major axis.
