Opening Exercise
1.) Scan the figures in the next several problems. How are
these diagrams different from the diagrams in Lesson 12?
2.) Does this changes the way you figure out whether a
condition exists that determines whether the triangles are
identical?

1.) Three Sides Condition
2.) Two Sides and an Included Angle Condition
3.) Two Angles and an Included Side Condition
4.) Two Angles and a Non­Included Side Condition
5.) Two Sides and a Non­Included Angle where the Angle is 900 or greater
Side WY is
shared and
therefore equal
The two triangles are
identical because they meet
the three sides condition.
