Similar Triangles TESTS(1) Corresponding sides are in proportion (SSS with ratio a:b)(2) Two pairs of corresponding sides are in proportion AND theincluded angles are equal (SAS with ratio a:b) 5. Similar Triangles TESTS(1) Corresponding sides are in proportion (SSS with ratio a:b)(2) Two pairs of corresponding sides are in proportion AND theincluded angles are equal (SAS with ratio a:b)(3) All three angles are the same as the three angles in the other (AA) 6. Similar Triangles TESTS(1) Corresponding sides are in proportion (SSS with ratio a:b)(2) Two pairs of corresponding sides are in proportion AND theincluded angles are equal (SAS with ratio a:b)(3) All three angles are the same as the three angles in the other (AA) e.g. Find ADC21 cmE15 cm A B D24 cm 7. Similar Triangles TESTS(1) Corresponding sides are in proportion (SSS with ratio a:b)(2) Two pairs of corresponding sides are in proportion AND theincluded angles are equal (SAS with ratio a:b)(3) All three angles are the same as the three angles in the other (AA) e.g. Find ADC DAE BAC common A21 cmE15 cm A B D24 cm 8.
