AA Similarity Criteria

If the scale factor is greater than one, the new figure will be

• reduction

• enlargement

• scale

• not proportional

What is the value of X?

• X=4

• X=6

• X=3

• X=2

Check whether pairs of triangles in the given figure are similar or not. If yes, identify the similarity criterion used by you for answering the question and also identify the pairs of similar triangles in the symbolic form.

• Not Similar

• Similar - SSS Criteria - ΔLMP∼ΔDEF

• Similar - SSS Criteria - ΔMLP∼ΔDEF

• Similar - AA Criteria - ΔLMP∼ΔFED

The pair of figures is similar. Find the missing side.
