Question

Jackie cut a piece of paper along its diagonal, as shown below, forming two triangles.

A rectangle is cut diagonally to form 2 equal triangles.

How do the height and base length of the two triangles compare to the height and base length of the original piece of paper?


The two dimensions are the same in the triangles as they were in the rectangle.

The two heights are the same in the triangles as they were in the rectangle, but the bases of the triangles are half the length of the base of the rectangle.

The two bases of the triangles have the same length as the base of the rectangle, but the triangles have heights equal to half the height of the rectangle.

The two dimensions of the triangles are each half what they were in the rectangle.

Answer 1

c is the correct answer

Explanation:

Answer 2

B. The two dimensions are the same in the triangles as they were in the rectangle.

Explanation:

Given

Initial Shape: Rectangle (Before cut)

Final Shape: Triangles (After cut)

Note that this can be explained properly with the use of attachments

See attachment 1 for Before Cut

Before Cut represent the full rectangle before Jackie cut the piece of paper.

Let H and B represent the height and base of the triangle

Given that the rectangle is cut diagonally, this means that the cutting starts and ends at the opposite edges of the rectangle

See attachment 2 for After Cut

After Cut represent the two triangles after cutting the rectangle

From the attachment, you'll observe that the dimension of the two triangles (Triangle 1 and Triangle 2) are the same as it is with the rectangle;

In other words, the two triangle have their heights as H and their bases as B.

Hence, it can concluded that the two dimensions are the same in the triangles as they were in the rectangle.
