We're learning about classifying triangles with Side-Angle-Side, Angle-Side-Angle, etc. I'm kind of confused-- I have the definitions, but when I am shown a picture, I have trouble figuring out which it is. Could you please explain it or provide a link with a thorough explanation? Thank you so much.
These sites should help you.

Of course! I'd be happy to explain the different methods of classifying triangles based on their side lengths and angle measures.
To determine the classification of a triangle, you need to consider the measures of its angles and the lengths of its sides. Let's go through the different classifications:
1. Side-Length Classifications:
- Equilateral Triangle: All three sides are equal in length.
- Isosceles Triangle: At least two sides are equal in length.
- Scalene Triangle: All three sides have different lengths.
2. Angle-Measure Classifications:
- Acute Triangle: All three angles are less than 90 degrees.
- Right Triangle: One angle measures exactly 90 degrees.
- Obtuse Triangle: One angle is greater than 90 degrees.
Now, let's look at the different methods of classifying triangles based on their side and angle combinations:
1. Side-Angle-Side (SAS):
- If you know that two sides of a triangle are proportional to the corresponding sides of another triangle, and the included angles between these sides are equal in measure, then you can classify the triangles using the SAS method.
2. Angle-Side-Angle (ASA):
- If you know that two angles of a triangle are equal in measure to the corresponding angles of another triangle, and the included side between these angles has the same length, then you can classify the triangles using the ASA method.
3. Side-Side-Side (SSS):
- If you know that all three sides of a triangle are proportional to the corresponding sides of another triangle, then you can classify the triangles using the SSS method.
To determine the triangle classification using these methods, try to identify the given side lengths and angle measures of the triangle you are looking at. Then, compare them to the conditions described for each classification.

This website provides detailed explanations and visual aids that can help you understand and remember the different classifications of triangles.
Remember, practice makes perfect! As you work with more examples and practice identifying the different classifications, it will become easier for you to recognize them.
