Math Problem Statement
Solution
The two triangles shown in the image both have one angle marked as , but there is no other information about the sides or the third angle.
To determine whether the triangles are similar, we can check the criteria for triangle similarity:
- AA (Angle-Angle) Similarity: If two angles in one triangle are congruent to two angles in another triangle, the triangles are similar.
- SSS (Side-Side-Side) Similarity: If all three sides of one triangle are proportional to the corresponding sides of another triangle, the triangles are similar.
- SAS (Side-Angle-Side) Similarity: If two sides of one triangle are proportional to two sides of another triangle and the included angle is congruent, the triangles are similar.
From the diagram, we only know one pair of angles (both marked as ), but there is no additional information about the other angles or sides. Based on this, there isn't enough information to use the AA, SSS, or SAS criteria. Therefore, the triangles cannot be confirmed as similar with the given data.
Thus, the correct answer is:
- C. Not similar
