Question

question 10 of 10
the shapes of the horizontal cross - sections of the cone below are all congruent except for the vertex.
a. true
b. false

Explanation:

Congruent shapes have the same size and shape. The horizontal cross - sections of a cone are circles. As we move up the cone (away from the base), the radius of the circular cross - sections decreases. So, the horizontal cross - sections (except the vertex, which is a point) are similar (same shape) but not congruent (different size).

Answer:

B. False
