Answer:
The statements which are correct are:
- It is enough to show that two pairs of corresponding angles are congruent.
- It is enough to show that all three pairs of corresponding sides are in the same ratio.
Step-by-step explanation:
If two triangles have two pairs of sides in the same ratio and the included angles are also equal, then the triangles are similar.
Two triangles are similar if they have:
- corresponding sides are in the same ratio
There are three ways to find if two triangles are similar: AA, SAS and SSS:
1)
It is enough to show that two pairs of corresponding angles are congruent.
because if two triangles will be congruent than automatically the third will also be congruent and hence we can apply AA similarity.
2)
It is enough to show that all three pairs of corresponding sides are in the same ratio.
Hence, it will imply SSS similarity.
Hence, these two conditions would be enough to show that the triangles are similar.
