1. Every plane section of a sphere is a circle 2. A plane through the apex of a cone gives a triangle 3. A cut parallel to a pyramid's base gives a figure identical to the base
Answer: D
Correct answer: 1 and 2 only are correct
Statements 1 and 2 are correct: every plane section of a sphere is a circle, and a plane through the apex of a cone gives a triangle. Statement 3 is the standard error - a cut parallel to a pyramid’s base is similar to it but smaller, and only a prism gives a section identical to its base.
