Congruent Figures Equal Size and Shape
SSS Postulate segment QN = segment QP segment YN = segment YP segment YQ = segment YQ Triangle QYN is congruent to triangleQYP by Side-Side-Side.
SAS Postulate • PQ = ST Both sides = 4 • angle Q = angle T Both angles =100 ̊ • QR = TV Both sides = 5 • Triangle PQR is congruent to triangle STV by Side-Angle-Side.
ASA Postulate • angle A = angle D • segment AP = segment DP Both sides = 5 • angle B = angle C • Triangle BAP is congruent to triangle CDP • by Angle- Side- Angle
AAS Postulate • angle A = angle Y (both are 75 ̊) • angle C =angle Z(both are 65 ̊) • segment AB =segment XY(both are 10cm) • Triangle CAB is congruent to triangle ZXY • by Angle-Angle-Side.
