    What is the angle-angle similarity postulate?

    When two triangles have corresponding angles that are congruent, right?

    Look it up and post it accurately.

    The AA similarity postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar

    So if you can show that two angles of the first triangle are congruent to two angles of the second triangle, then you can state that the triangles are similar by the AA similarity postulate.

    In other words, they have equal measures.

    Now, can you show that two angles are congruent?

    well i know ab and a'b' have the same measurements

    Is 32 degrees equal to 32 degrees?

    So do angles A and A' have the same measure?

    So are angles A and A' congruent since they have the same measure?

    Now we have shown 1 angle of the first triangle is congruent to 1 angle of the second triangle. How many angles must we show are congruent to have AA similarity?

    2 and both b and b' have the same measurements

    That would be B and B'. You are not allowed to change the name of the angle.

    oh sorry

    So now, having shown that angles A and A' are congruent and B and B' are congruent, you can state that the two triangles are similar because of the AA similarity postulate.

    And I hope you have discovered that even the simplest geometry problem is impossible if you don't know the meaning of the words.
