而由點和線段 再加上角 組成的圖形

And the figure composed of a point, a line segment, and an angle

點 線段與角之間的關係也很有趣

The relationship between point, line segment, and angle is also very interesting

便稱為多邊形

It is called a polygon

以等腰三角形ABC舉例

Taking the isosceles triangle ABC as an example

真是的!!!每次都打著學習名義實際上只是想愛愛而已

Really!!!Every time it's under the guise of studyingbut actually just want to have sex

以A為頂點的角稱為角A

The angle with vertex A is called angle A

線段AB及線段AC為角A的兩邊 「線段AD=線段BD(對稱線段等長) 角ACD=角BCD(對稱角相等) 角A=角B(兩底角相等)

Line segments AB and AC are the two sides of angle A. "Line segment AD = line segment BD (symmetric line segments of equal length) Angle ACD = angle BCD (symmetric angles are equal) Angle A = angle B (equal base angles)"

這次絕對不會 再跟你做啦

I won't do it with you again this time

而摺疊後可使 兩側圖形完全重疊之線段我們稱其為·

The line that allows the two sides of the figure to completely overlap is called ·

聽我說話 啊啊啊啊

Listen to me talking, AAAAaaa
