Question

Identify the 2-dimensional shape created from a diagonal cross section of a cone​

Answer 1

Answer:

An ellipse

Step-by-step explanation:

Take a cone and make a diagonal cut through it, removing a very thin slice.  The result is an ellipse.  

 

a      /\

     /    \

   /        \   b      

 /            \    

Make a straight line from a to b, it will make an elliptical shape.  If we cut perfectly horizontally, we would get a circle, when we angle the cut of our cross section, the shape gets more and more elliptical depending on the angle of the cut
