Math Problem Statement
State if the triangles are similar. If so, state the postulate and the similarity statement.
Solution
To determine if the triangles and are similar, let's analyze the information provided in the image.
Given Data:
We need to check if the two triangles share any of the known similarity postulates (AA, SSS, or SAS):
Step 1: Identify the Angles
- In , one angle is given.
- In , one angle is given.
Step 2: Check the Relationship Between Angles
To determine if the triangles are similar by the AA (Angle-Angle) postulate, we need to verify if the angles in and are congruent.
- is a vertical angle with . Therefore, .
- The sum of angles in must be . Thus, the angle can be found as:
Step 3: Conclude the Similarity
- and both have angles and .
- This gives us two pairs of congruent angles.
Conclusion:
Since and have two corresponding angles that are congruent, the triangles are similar by the AA (Angle-Angle) Similarity Postulate.
