数学学习离不开解题,解题能检验学生掌握知识的深浅程度,也能考查学生的思维品质,还可使学生享受到不同品味的解题艺术。近年来,全国各地中考和竞赛试题,涉及判定三角形形状的问题屡见不鲜。本文主要谈谈判定三角形形状的解题方法。1借助韦达定理例1已知θ是三角形的一个内角,且sinθ和cosθ是一元二次方程2x~2-2x+p=0的两个实数 Mathematical learning is inseparable from the problem-solving, problem-solving can test the degree of students mastery of knowledge, but also to examine the thinking quality of students, but also enable students to enjoy different taste of the art of problem-solving. In recent years, exams and competitions throughout the country, questions related to determining the shape of the triangle are commonplace. This article mainly talks about the method of solving triangle shapes. 1 With Vedant Theorem 1, it is known that θ is an interior angle of a triangle, and sin θ and cos θ are two real numbers of the quadratic equation 2x ~ 2-2x + p = 0
