To explain:
SAS or SSS inequality theorem are effective for keeping a newly planted tree perpendicular to the ground.
Answer to Problem 56SPR
The
Explanation of Solution
Given information:
By the SAS Inequality Theorem, if the tree started to lean, one of the angles of the
However, with one end of the long wooden stake in the ground and the other end tied to the tree, no side of the triangle can change length. Thus, no angle can change.
This ensures that if the tree were perpendicular to the ground when the stake was attached, then it will remain perpendicular to the ground.
