Does matching one measurement mean congruent
Two triangles each have one angle of exactly 40°, at a labeled vertex, and nothing else is known about either triangle. Are the two triangles guaranteed to be congruent?
Correct.This lesson is now marked done.
Not quite.Try again, or ask for a hint.
The dragging widget in this lesson showed one shared length still allowing many different triangles. Ask whether fixing one angle instead is any different: does anything stop the other two sides from still varying freely?
