COMMENTS
|
Which two sides are the long sides and which side is the short side, or equivalently which angles are the wider angles and which angle is the narrower angle, is the only relevant information to consider for each triangle. Triangles are all assumed isosceles and congruent to one another.
All examples in this Problem feature four of these triangles connected by corners and/or edges. |

Which two sides are the long sides and which side is the short side is the only relevant information to consider for each triangle; proportions of sides and angles need not be accurate. Triangles are all assumed isosceles, congruent to one another, and to have the correct proportions.
All examples in this Problem feature four isosceles triangles connected by corners and/or edges. |

All examples in this Problem feature four isosceles triangles connected by corners and/or edges; were they equilateral, they would be able to be folded into a regular tetrahedron. |
