CODE RED YELLOW – DO NOW •

CONGRUENT TRIANGLES REVIEW SOL G. 6 LEARNING TARGET: BY THE END OF CLASS TODAY, I WILL BE ABLE TO PROVE TWO TRIANGLES ARE CONGRUENT, USING ALGEBRAIC AND COORDINATE METHODS AS WELL AS DEDUCTIVE PROOFS BY ANSWERING QUESTIONS COLLABORATIVELY AS A CLASS AND THEN ANSWERING 6 OUT OF 8 QUESTIONS CORRECTLY ON AN EXIT TICKET. ESSENTIAL QUESTIONS: HOW CAN YOU PROVE TWO TRIANGLES ARE CONGRUENT? HOW CAN YOU IDENTIFY CORRESPONDING PARTS OF CONGRUENT TRIANGLES?

CODE YELLOW There are 5 WAYS to PROVE TRIANGLES are CONGRUENT: SSS : all sides are congruent SAS : two sides and the angle between them are congruent ASA : two angles and the side between them are congruent AAS : two angles and an attached side are congruent HL : the hypotenuse and one leg are congruent

CODE YELLOW Vocabulary Right Triangle – A triangle with one right angle Hypotenuse – the longest side of a right triangle Legs – the other two sides of a right triangle
