有兩平行線被一直線所截
設所截兩點為A,A'
兩組同側內角的角平分線交點為B,B'
角ABA'和角AB'A'為90度
所以角BAA'+角BA'A=90度,角B'AA'+角B'A'A=90度
又角BA'A'=角DAA',角B'A'A=角BAA'
所以角BAB'=角BA'B'=90度
又角BCA=角DAC,角DCA=角BAC
所以角BAD=角BCD=90度
(C)長方形

直線又不一定要垂直兩平行線

(有圖會比較清楚我在說什麼)
有兩平行線被一直線所截
設所截兩點為A,C
兩組同側內角的角平分線交點為B,D
角ABC和角ADC為90度
所以角BAC+角BCA=90度,角DAC+角DCA=90度
又角BCA=角DAC,角DCA=角BAC
所以角BAD=角BCD=90度
如果角BAC角=BCA=角DAC=角DCA=45度
則為正方形
但是題目沒有類似的條件
所以為長方形

(數學)
是長方形....
由同側內角平分線圍成的
同側內角合為180度,平分之後為90
所以另一個角度為90度
四個90度的角即為長方形.....但不一定是正方形
如果兩條平行線越靠近則長與寬的比例會越來越大
