读了《中小学数学》2011年第10期《有待商榷的命题改写》一文,很受感触,笔者也想谈点自己的看法.例习题(原文)判断下列语句是不是命题,如果是命题,请将其改写成:“如果……那么……”的形式.三角形的内角和为180°.角平分线上的点到这角两边的距离相等.一个角的补角大于这个角.陈老师认为例习题应该改为:如果是三角形的内角和,那么这个和为180°.如果是角平线上的点,那么它到这角两边的距离相等.如果是一个角的补角,那么它就大于这个角.我认为例习题应该改为:如果三个角的和是一个三角形的内角和,那么它
Read the “primary and secondary mathematics” 2011 the tenth period “to be open to revising the proposition,” a text, very touched by, I would like to talk about their own point of view. Exercises (Original) Judgment of the following statement is not a proposition, if proposition, Please rewrite it as: “If ... then ...” The interior angle of the triangle is 180 ° The distance from the point on the bisector to the distance on either side of this corner is equal, and the complementary angle of one corner is greater than this angle. Chen think the example exercises should be changed to: If it is the triangle and the inner angle, then this sum is 180. If it is a point on the angle of the line, then it is equal to the distance between the two sides of this corner.If it is a corner of the supplementary angle, Then it is greater than this angle .I think the example exercises should be replaced by: If the sum of the three corners is a triangle and the angle, then it
