Question Fold a rectangular sheet of paper, then draw a line along the fold created. Name and compare the angles formed between the fold and the sides of the paper. Make different angles by folding a rectangular sheet of paper and compare the angles. Which is the largest and smallest angle you made?
Let’s mark the rectangle and vertex of the fold as shown in figure below.
We get ∠1, ∠2, ∠3 and ∠4.
Comparing: ∠1 < ∠2, ∠4 < ∠3,
∠1 = ∠4, ∠2 = ∠3.
∠2 and ∠3 are the largest angles.
∠1 and ∠4 are the smallest angles.
