a square pyramid is cut perpendicular to its base and through the vertex.What two-dimensional figure is formed by the cross section ?
a)parallellogram
b)rectangle
c)square
d)triangle
sketch it. Triangle of course.
a trapezoid your welcome
To determine the two-dimensional figure formed by the cross section of the square pyramid, we first need to understand how the cut is made.
When a square pyramid is cut perpendicular to its base and through the vertex, the resulting cross section will pass through the center of the base and form identical triangles on each side.
This means that the answer is a triangle (option d). The cross section will be a triangle because cutting perpendicular to the base will create congruent (identical) right triangles on each side of the cut. Therefore, the correct answer is d) triangle.
