Triangle Classification and Congruence Test Review

Learn to classify triangles by sides and angles as equilateral, equiangular, scalene, or obtuse. Identify corresponding congruent parts: sides PQ=XY, QR=YZ, RP=XZ; angles <P=<X, <R=<Z, <Q=<Y. Test congruence with SAS criteria and solve for missing angles.

  1. Review for test

  2. Classify each triangle by sides AND angles Equilateral, Equiangular Scalene, Obtuse

  3. x = 7, m<ABC = 125o y = 8, m<M = 51o y = 60

  4. Identify all pairs of corresponding congruent parts Sides Angles PQ=XY QR=YZ RP=XZ <P = <X <R = <Z <Q = <Y

  5. x = 6 Find if the triangles are congruent Why Write a congruent statement Yes 72 = 72, so SAS ACB = XZY

  6. 100o 13.5 -5

  7. Are the triangles congruent? Why? Write a congruent statement
