Chapter 4.2, Problem 11WE

To determine

Whether the $\Delta ABC$ is congruent to another triangle by SSS, SAS, or ASA postulates.

Answer to Problem 11WE

  $\Delta ABC\cong \Delta BST$ by SSS postulates.

Explanation of Solution

Given information :

The given figure is,

From the given figure it is clear that in both the triangles $\Delta ABCand\Delta BST$

  $\begin{array}{l}BC=ST\\ AB=BS\\ AC=BT\end{array}$

Therefore, by SSS postulates $\Delta ABC\cong \Delta BST$
