Question

question 7 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:

Step1: Recall cone cross - section property

Horizontal cross - sections of a cone are circles. As we move from the base to the vertex of a cone, the radius of the circular cross - sections decreases.

Step2: Define congruence

Congruent shapes have the same size and shape. Since the radii of the circular cross - sections of a cone change as we move towards the vertex, the cross - sections are not all congruent.

Answer:

B. False
