To Describe:Structures that are built usingcongruent

Answer to Problem 28HP
Roof ends
Explanation of Solution
Given: Describe structures that are built using the congruent triangles. Explain why you think congruent triangles are used.
There are many real world examples of the congruent triangles.
Building and bridges are made using the congruent triangles.
Another example:
Roof ends
The roof ends are the congruent so the beam and the top edges of the wall are horizontal.
The triangles are congruent when the corresponding sides are equal. So they easily overlap.
The congruent triangles are used because they considered more stable and strong to use.
