Question

question 1 of 10
the vertical cross - sectional shapes of this prism are all congruent triangles.
a. true
b. false

Explanation:

Step1: Recall the property of a prism

A prism has two congruent and parallel bases.

Step2: Analyze the vertical cross - section

For a triangular prism (the given prism), the vertical cross - sectional shapes (parallel to the bases) are congruent to the bases. Since the bases of a triangular prism are triangles, the vertical cross - sectional shapes are congruent triangles.

Answer:

A. True
