AA
Determine whether the pair of triangles is similar. Justify your answer (AA Sim, SSS Sim, SAS Sim)
Yes, SAS Sim (3 to 2 ratio)
Determine whether the pair of triangles is similar. Justify your answer (AA Sim, SSS Sim, SAS Sim)
AA postulate: ∆RST ∼∆NOP
Yes, ∆RKS ∼∆LPD
AA similarity
if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar
SSS similarity
if three sides of one triangle are proportional to the three corresponding sides of another triangle, then the triangles are similar
SAS (1 to 2 ratio)
if two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar
