Co-vertices are the **endpoints of the minor axis** .

#### Explanation:

Co-vertices are the **endpoints of the minor axis** .

Let us consider an ellipse described by

graph{x^2/16+y^2/9=1 [-10, 10, -5, 5]}

This is an ellipse with horizontal orientation and as can be seen its co-vertices are

Now consider another ellipse

graph{(x+3)^2/9+(y-4)^2/25=1 [-12.34, 7.66, -1, 9]}

This is an ellipse with vertical orientation and as can be seen its co-vertices are
