+400 The left column contains pairs of triangles with different side-length and angle-measure congruences marked. Match each diagram in the left column with a congruence/similarity criterion in the right column that justifies why the two triangles are congruent/similar. Duplicates are NOT permitted. Note: to undo a connection, click the link itself, not one of the boxes in the columns.
+6 To solve this question, look at each pair of triangles in the left column and check what is marked sides or angles. Then match each pair with the correct rule from the right column that explains why the triangles are congruent or similar. Use criteria like SSS (side-side-side), SAS (side-angle-side), ASA (angle-side-angle), AAS (angle-angle-side), or AA (angle-angle for similarity). Each rule can be used only once, so do not repeat them. To remove a wrong match, click the line between the boxes.
