There are several online resources that can help 9th-grade geometry students understand the SAS (Side-Angle-Side) congruence theorem, complete with visual examples and practice questions, including multiple-choice formats. Here are some recommended resources:
1. **Khan Academy**:
- [SAS Congruence](https://www.khanacademy.org/math/geometry-home/triangle-similarity/triangle-congruence/v/congruence-sas) - This video explains the SAS congruence theorem with visuals and examples. Khan Academy also offers practice exercises that may include multiple-choice questions.
2. **IXL**:
- [IXL Geometry](https://www.ixl.com/geometry) - While IXL is a subscription service, it offers a variety of geometry practice problems, including SAS congruence, with instant feedback. There may be various question types including multiple-choice.
3. **Math is Fun**:
- [Math is Fun - Congruent Shapes](https://www.mathsisfun.com/geometry/congruent.html) - This site provides straightforward explanations along with visual aids. Check if there are links to practice problems as well.
4. **Teacher Pay Teachers**:
- Look for downloadable resources titled "SAS Congruence Theorem" or "Triangle Congruence." Many educators post free resources that include visuals, practice problems, and sometimes interactive elements.
5. **GeoGebra**:
- [GeoGebra Geometry](https://www.geogebra.org/geometry) - This is a dynamic geometry software that allows users to visualize and manipulate figures. You can create your own constructions to demonstrate the SAS theorem or explore shared resources.
6. **Quizizz**:
- Search for quizzes related to the SAS congruence theorem. These often include multiple-choice questions and provide an interactive way to test knowledge.
7. **Quizlet**:
- [Quizlet Study Sets](https://quizlet.com/) - There may be study sets and flashcards focusing on the SAS theorem, with visuals and practice questions.
8. **YouTube**:
- Search for videos that specifically cover the SAS theorem in geometry. Look for channels that are educational and aimed at high school math, as they often have clear examples and explanations.
These resources should provide a comprehensive understanding of the SAS congruence theorem, coupled with visual aids and opportunities for practice through multiple-choice questions.
