same shape
same size
Is a Scale factor of 2 an enlargement or a reduction?
*
1 point
enlargement
reduction
Is the scal factor of 1/4 a reduction or enlargement?
*
1 point
enlargement
reduction
Which one of these are not a Similarity Theorem
*
1 point
AA
SAS
AAS

Answer 1

1) Not required to be similar: same size — similarity needs same shape/angles congruent, not same size.

2) Scale factor 2: enlargement (since >1).

3) Scale factor 1/4: reduction (since <1).

4) Not a similarity theorem: AAS — AA and SAS are similarity criteria; AAS is a congruence condition, not a similarity theorem.
