2. Why does a Scissor illustrate hinge theorem?
3. Why does a folder illustrate hinge theorem?​

Answer 1

Answer:

1. To illustrate this, think about the trap door again. When we open it, we create a triangle. One side is the door, one side is the floor length of the door, and the third side is the opening length. The wider you open the door, the greater the hinge angle and the greater the opening length.

2.The "included angle" is the angle formed by the two sides of the triangle mentioned in this theorem. This theorem is called the "Hinge Theorem" because it acts on the principle of the two sides described in the triangle as being "hinged" at their common vertex. ... (May also be referred to as the SSS Inequality Theorem.)

3. We have seen how inequalities can be applied to the sides and angles of a single triangle. ... This theorem is called the "Hinge Theorem" because it acts on the principle of the two sides described in the triangle as being "hinged" at their common vertex.
