2. Similar Triangles TESTS 3. Similar TrianglesTESTS (1) Corresponding sides are in proportion (SSS with ratio a:b) 4. Similar TrianglesTESTS (1) Corresponding sides are in proportion (SSS with ratio a:b)(2) Two pairs of corresponding sides are in proportion AND the included angles are equal (SAS with ratio a:b) 5. Similar TrianglesTESTS (1) Corresponding sides are in proportion (SSS with ratio a:b)(2) Two pairs of corresponding sides are in proportion AND the included 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 TrianglesTESTS (1) Corresponding sides are in proportion (SSS with ratio a:b)(2) Two pairs of corresponding sides are in proportion AND the included 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 AD C 21 cm E 15 cmA BD 24 cm 7.
