please check:
this deals with a rectangular prism:
RECTANGULAR PRISM HAS (6 FACES)
4 FACES ARE FORMED BY RECTANGLES
2 FACES ARE FORMED BY SQUARES
A RECTANGULAR PRISM HAS 12 EDGES
A RECTANGULAR PRISM HAS 8 VERTICES
t FOR TRUE, f FOR FALSE
T : IT HAS NO CURVED SURFACES
T: ALL OF THE EDGE ARE PARALLEL
T: ALL THE FACES ARE POLYGON
f: ALL THE FACES ARE CONGRUENT
BUT MY TEACHER SAID THERE ARE 2 F AND 2 T
Are ALL edges parallel?

Let's go through each statement one by one and determine if it is true or false.
Statement 1: "It has no curved surfaces" - The statement is true. A rectangular prism consists of flat surfaces that are rectangles or squares. There are no curved surfaces in a rectangular prism.
Statement 2: "All of the edges are parallel" - The statement is true. In a rectangular prism, all the edges are parallel to each other. This is because the opposite sides of each face are parallel.
Statement 3: "All the faces are polygons" - The statement is true. A polygon is a closed figure with straight sides. In a rectangular prism, all the faces are either rectangles or squares, which are examples of polygons.
Statement 4: "All the faces are congruent" - The statement is false. In a rectangular prism, the faces are not always congruent. The opposite faces of a rectangular prism are congruent, but the adjacent faces are usually not congruent.
Based on these explanations, it seems like your teacher is correct. Statements 1, 2, and 3 are true, while statement 4 is false.
