) Match the following up top to the terms on the bottom:Triangle, Circle, Sphere, Great circle, Ellipse. a. diagonal cross section of a cylinder b. cross section parallel to the base of a cone c. shape created when a semi-circle is rotated about the y-axis d. diagonal cross section through the widest part of a sphere e. perpendicular cross section of a cone

a. Ellipse.

b. Circle.

c. Sphere.

d. Great circle.

e. Triangle.

Step-by-step explanation:

a. As seen below, if you have a cylinder, and you diagonally cut it, you will have an ellipse.

b. If you cut a cone parallel to its base, you will have a circle.

c. When you rotate a semi-circle around an axis, you will have a sphere.

d. A great circle is the intersection of the sphere and a plane that passes through the center point of the sphere. So, it is the diagonal cross section through the widest part of the sphere.

e. When you cut a cone perpendicular to the base, you get a triangle.

Hope this helps!
