1. Applying Similarty Using the Angle-angle (AA) criterions
~adapted from walch education

2. Angle-Angle (AA) Similarity Statement
If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
it is not necessary to show that the third pair of angles is congruent because the sum of the angles must equal 180˚.

3. Practice #1 Explain why , and then find the length of
Hint: Similar triangles have corresponding sides that are proportional.

4. Solution Show that the triangles are similar. Find the length of
Since and , then by AA Similarity Statement
Find the length of
(2.72)(6.9) = (3.4)(x)
x = 5.52
