数学教学离不开解题,解题可以训练学生的数学思维方法,也可以培养学生创造性的思维能力,而现实中,学生对几何类的题目最怕,复杂的几何图形将学生弄得头昏脑胀,几何题中又以动点等动态问题最难,经常让学生丈二和尚摸不着头脑.动态几何是研究在几何图形的运动中,伴随着出现一定的图形位置、数量关系的“变”与“不变”性;就其运动对象而言有点动、线动、面动;就其运动形式而 Mathematical teaching can not do without problem solving, problem solving can train students 'mathematical thinking, can also cultivate students' creative thinking ability, but in reality, students are most afraid of the problem of geometric class, complicated geometry make students dizzy Brain swelling, geometric problems with moving points and other dynamic problems the most difficult, often let the student husband Zhang two monks puzzled. Dynamic geometry is the study of geometric movement, accompanied by a certain number of graphics position, the number of relations “And ” unchanged "sex; in terms of their movement in terms of a little move, line move, face move; in its movement and
