we know that
In this problem the answer is true
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
so
If F is similar a G and G is similar a H , then F is similar a H
answer is true
Problem N 2
Remember that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem we have that
triangle CAS is similar to triangle TEC
that means
and
CA/TE=AS/EC=CS/TC
so
Its not always true
