____1. What shape will be formed after dividing a square diagonally?
• Triangles are formed when you divide a square diagonally. To be specific, the triangles formed are congruent. It is applicable for all kinds of parallelogram.

____2. How many triangles can you make if you divide a trapezoid diagonally?
• If you divide a trapezoid diagonally, you'll have two triangles as a result, they are not congruent. Thus, two diagonals will divide the trapezoid into four triangles.

____3. How many triangles can be formed in a parallelogram.
• A parallelogram can always be divided into two identical or congruent triangles by a segment that connects opposite vertices, a diagonal.

____4. If you divide the rectangle vertically what shape will be the result?
• The resulting shape is still a rectangle. Note that a square can be classified as a rectangle.
[tex]\blue {\overline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: }}[/tex]
____5. Compare a square and a rectangle. What is common to both figures?
• They are both parallelograms. A square is a rectangle yet does not guarantee that all rectangles are square. Both have four congruent interior angles, 90° each. Their opposite sides are parallel to each other and their diagonals bisect each other.
