Triangle congruence and similarity MATH · 10TH GRADE Name Date TAKE-HOME PRACTICE Math · 10th Grade 30 minutes WHAT THIS BUILDS Applies the congruence and similarity criteria correctly and knows why SSA fails. 1 THE TWO-MINUTE CHECK ASK "Which criteria prove congruence? Why isn't SSA one of them?" A SOLID ANSWER SSS, SAS, ASA, AAS, HL — and can describe or draw the SSA ambiguity. Not yet Getting there Solid 2 BUILD THE AMBIGUOUS CASE You need: Straws or strips of card, A protractor, Paper Build triangles from given measurements and see which sets force a unique triangle. Try SSA and physically construct two different triangles from the same data. That construction is the reason the criterion doesn't exist — no memorisation needed. Use similarity to find a real height by shadow or by a mirror on the ground. Write one proof using each criterion. SAY THIS WHEN IT STALLS "Build it with the straws. Can you make two different triangles from that data? Then it can't be a rule." Identify which criterion applies to given diagrams. Proofs requiring two triangles and an intermediate result.
