To explain : The reason for the congruency of the four
Answer to Problem 18PSB
The triangles are congruent by SSS property
Explanation of Solution
Given information : The information is given regarding the triangles and the pyramid
The base of the pyramid is a square
All four triangles of the pyramid are isosceles triangles
Let the edge of the pyramid be x . now, we know that as all the edges are the sides of the triangles that are in common, we can say that
For any triangle, both vertical sides are congruent
Now, we know that the base of the pyramid is a square. Thus, we can say that
All the bases of these isosceles triangles are also congruent
Now, given that we know that all the three sides of all of these triangles are congruent, we can say that
The triangles are congruent by SSS property
