1.Construct the perpendicular bisector of the linePQ.Label the mid-point of the line PQ,A
2.Extend the perpendicular bisector to meet the line RS at B
3.Bisect the angle BAQ and extend the angle bisector to meet QR at point C
4.At C, construct a perpendicular to the line QR that meets AB at point D and PS at E
5.With C as its centre and radius CD,draw an arc DF so that F is between C and R
6.Translate the line CD 2cm to the right and label it C'D'
7.Translate the arc DE 2cm to the right and Label it D'F'
8.Shade the region between the arc DF and its translation
9.Reflect the shaded region in the line AB
10.Rotate the line AC clockwise through 90° about the point C.5
P.S.只有單字方面要翻譯 英文字母單一或是兩個只要是大寫的都不用翻譯 謝謝各位大哥
