         <description><![CDATA[<p>우리가 기하를 배우는 이유는 단순히 도형의 성질을 외우기 위해서가 아니다. 기하는 공리와 정리를 바탕으로 논리적으로 사고하는 과정을 통해 논리적 추론 능력을 길러준다. 또한 도형과 입체를 다루면서 공간 감각을 발달시키고, 건축·공학·디자인 등 다양한 분야에서 활용할 수 있는 기초를 마련해 준다.</p><p><br/></p><p>더 나아가 기하는 면적, 부피, 거리 계산처럼 실생활 문제 해결과도 직접 연결된다. 내비게이션, 컴퓨터 그래픽스, 건축 설계 등 여러 기술 속에도 기하학적 원리가 숨어 있다. 또한 기하는 대수, 미적분, 삼각함수와 자연스럽게 이어져 수학의 다른 영역을 이해하는 데 다리가 되어 준다.</p><p><br/></p><p>따라서 기하를 배우는 것은 단순한 도형 학습이 아니라, 논리적 사고력과 공간적 이해력, 그리고 창의적인 문제 해결 능력을 함께 키워 주는 의미 있는 과정이라고 할 수 있다.</p>]]></description>

         <description><![CDATA[<p>기하를 배우는 이유는 단순히 수학 시험을 잘 보기 위해서만은 아니다. 기하는 도형의 성질을 탐구하고 공간을 이해하는 과정에서 논리적으로 사고하는 힘을 길러준다. 예를 들어, 삼각형의 닮음이나 피타고라스 정리를 통해 문제를 풀다 보면 단순한 계산을 넘어 원리와 과정을 따져야 하기에 사고력이 깊어진다. 또, 건축이나 디자인, 컴퓨터 그래픽 같은 실제 생활 속에서도 기하적 원리가 많이 사용된다. 이런 점에서 기하는 우리에게 단순한 지식이 아니라 사고의 틀을 만들어 주고, 세상을 바라보는 시야를 넓혀 주는 과목이라고 생각한다.</p>]]></description>

         <title>1. 2차원 평면에서 직선의 기울기와 방향벡터기울기는 직선이 얼마나 기울어져 있는지를 나타내고, 방향벡터는 직선이 어떤 방향으로 뻗어 있는지를 보여준다.                                                         2. 3차원에서 주어진 벡터에 수직인 벡터수직인 벡터는 서로 직각을 이루는 벡터이다. 두 벡터가 수직이면 서로의 방향에 전혀 겹치는 부분이 없는 것처럼 생각할 수 있다.                                            3. 3차원에서 한 점과 법선벡터가 주어졌을 때법선벡터는 평면이 어느 방향으로 서 있는지 알려준다. 그래서 한 점과 법선벡터가 있으면 그 평면을 나타낼 수 있다.</title>
