การทำความเข้าใจเรื่องสามเหลี่ยมคล้ายเป็นเรื่องจำเป็นมากสำหรับนักเรียนที่เตรียมตัวสอบ เพราะหลายข้อสอบมักออกเป็นโจทย์ให้วิเคราะห์รูปสามเหลี่ยมและใช้สูตรเทียบสัดส่วน เพื่อหาคำตอบอย่างรวดเร็ว เทคนิคเพิ่มเติมที่อยากแนะนำคือ การทำ mind mapping เพื่อช่วยสรุปสูตรและความสัมพันธ์ของแต่ละส่วนประกอบในสามเหลี่ยมคล้าย เช่น ความสัมพันธ์ด้านมุมและด้านยาว รวมถึงวิธีการพิสูจน์ว่ารูปไหนคล้ายกัน โดยวิธีนี้ช่วยให้เราจำง่ายและประยุกต์ใช้ได้ทันที นอกจากนี้ การฝึกทำใบงานเกี่ยวกับความเท่ากันทุกประการจะช่วยเพิ่มความเข้าใจว่ารูปสามเหลี่ยมใดมีสัดส่วนและมุมที่เหมือนกันอย่างไร ซึ่งในระดับชั้น ม.2 นี้เป็นพื้นฐานสำคัญในการลงทุนเวลาฝึกฝน จากประสบการณ์ของผู้สอน ควรจับคู่แต่ละสูตรกับตัวอย่างโจทย์ที่หลากหลาย เพื่อให้พร้อมรับมือกับโจทย์หลอกหรือโจทย์ที่ซับซ้อนขึ้นในข้อสอบจริง โดยเฉพาะข้อที่ให้เลือกรูปสามเหลี่ยมที่ไม่ได้คล้ายกับรูปอื่น เช่นในข้อสอบ SMTE U 66 ที่ต้องวิเคราะห์ความแตกต่างด้านสัดส่วนและมุมอย่างละเอียด ท้ายสุด อย่าลืมฝึกเฉลยโจทย์จากข้อสอบเก่า เพราะจะช่วยให้เข้าใจแนวทางการตั้งโจทย์และวิธีคิดที่ถูกต้องมากขึ้น ซึ่งจะทำให้คุณสามารถทำคะแนนได้ดีในวันสอบจริง

Right triangle relations based on similarity

In any right triangle, dropping the lone altitude (the only one that crosses the interior of the triangle) produces many relations including the Pythagorean Theorem and the Reciprocal Pythagorean Theorem. One of my favorite formulae from geometry that the distance of the lone altitude can be found

A handwritten mathematical derivation on lined paper showing the distance between the orthocenter (O) and circumcenter (P) of a triangle. It uses the property a²+b²+c²=7R² to simplify Euler's theorem, concluding that OP = R√2 for a heptagonal triangle.

Simplifying the distance between two points in the heptagonal triangle

In a prior post, I derived the distance formula between the orthocenter and the circumcenter using a complicated argument involving similar triangles. In this post, I used a simple formula to get the required answer. #math #maths #maths #geometry #trigonometry

A handwritten math solution on lined paper, featuring a triangle diagram with orthocenter (O) and circumcenter (P) labeled. It derives the formula for the squared distance between them, d² = 9R² - (a²+b²+c²), using trigonometric identities and cosine rules.

The distance between the orthocenter and the circumcenter of a triangle

In any acute triangle, the distance between the orthocenter and the circumcenter is found with quite a nice formula that relate the sides and the circumradius. #math #maths #mathematics #geometry #trigonometry

A handwritten page showing the initial steps of deriving Heron's formula. It includes a triangle with its circumcircle, the formula for the circumradius R, cosine rules, and the derivation of partial areas (Δa, Δb, Δc) using R and trigonometric identities.

Deriving Heron’s formula using the circumradius of the triangle

Heron’s formula is a useful formula to find the area of a triangle using only the triangle’s side lengths. This is a lesser-known derivation of the formula, but quite a cool one nonetheless. #math #maths #mathemati cs #geometry #trigonometry

Proving the existence of the Gergonne point of a triangle

The Gergonne point is where three specific segments are concurrent. These segments come off the vertices and intersect where the incircle is tangent to the side opposite of the vertex. While not as well-known as the most well-known triangle centers, its existence is easily proven with Ceva’s theore
