Understanding student thinking is important, especially regarding triangle material as it is a basic concept in geometry that forms the foundation for advanced geometry learning. The purpose of this research is to analyze junior high school students' thinking in solving triangle problems based on the Geometric Habits of Mind (GHoM) framework. In other words, this research identifies the GHoM components that emerge when junior high school students solve triangle problems. This research was conducted from November 2024 to January 2025 at MTsN 2 Kediri City. The research approach used was qualitative. The research subjects were ten eighth-grade students. The research instruments were triangle test questions, interview guidelines, GHoM indicator rubrics, recording devices, and notebooks. The results showed that the ability of reasoning with relationships was the most achieved GHoM indicator among the subjects, followed by balancing exploration and reflection.
BAHASA INDONESIA ABSTRACT: Pemahaman terkait berpikir siswa penting, terutama materi segitiga karena merupakan konsep dasar dalam geometri yang menjadi fondasi bagi pembelajaran geometri lanjutan. Tujuan penelitian ini adalah untuk menganalisis berpikir siswa SMP dalam menyelesaikan soal segitiga berdasarkan kerangka Geometric Habits of Mind (GHoM). Dengan kata lain, penelitian ini mengidentifikasi komponen-komponen GHoM yang muncul ketika siswa SMP menyelesaikan soal segitiga. Penelitian ini dilaksanakan pada bulan November 2024 sampai Januari 2025 di MTsN 2 Kota Kediri. Pendekatan penelitian yang digunakan adalah kualitatif. Subjek penelitian adalah sepuluh siswa kelas VIII. Instrumen penelitian ini adalah instrumen soal tes segitiga, pedoman wawancara, rubrik indikator GHoM, alat perekam, dan buku catatan. Hasil penelitian menunjukkan bahwa kemampuan reasoning with relationships merupakan indikator GHoM yang paling banyak tercapai pada subjek, diikuti oleh balancing exploration and reflection.
