Little Slip 3: Solve each problem given.
1. Are the triangles similar? If so, write the
similarity statement and state the postulate or
theorem for justification. If not, why not?
2. Are the triangles similar? If so, write the
similarity statement and state the postulate or
theorem for justification. If not, why not?
3. Two right triangles have an acute angle with
the same measure. Name the theorem or
postulate that is the most direct way to prove the
triangles similar.

1.
True; Cross Product Property

3.
False; the cross product equation is NOT
equivalent to this equation.
4.
True; the cross product equation is equivalent to
the original proportion.
True; the cross product equation is equivalent to
