我是一名主播 请帮我生成一段关于图片中题目的讲解视频 要求配文字 要生动---**Extraction Content:** **Question Stem:** 如图，正方形ABCD的边长是6cm，三角形乙的面积比三角形甲的面积大6cm²，CE的长度是多少厘米？ **Other Relevant Text:** * Units mentioned: cm (centimeters), cm² (square centimeters). **Chart/Diagram Description:** * **Type:** Geometric figure. * **Main Elements:** * **Shapes:** * A square named ABCD. * A triangle labeled "甲" (Jia) which is formed by vertices A, D, and F. * A triangle labeled "乙" (Yi) which is formed by vertices C, E, and F. * **Points:** * A, B, C, D are the vertices of the square, arranged counter-clockwise (A top-left, B bottom-left, C bottom-right, D top-right). * Point F is located on the side CD of the square. * Point E is located on the extension of the line segment BC, such that C is between B and E. * **Lines:** * Sides of the square: AB, BC, CD, DA. * A straight line segment AE, which passes through point F. * Line segments DF, FC, CE form parts of the sides of the triangles and the square. * **Labels and Annotations:** * The square is labeled with its vertices A, B, C, D. * Inside the triangle ADF, the character "甲" is present. * Inside the triangle CEF, the character "乙" is present. * **Relative Position and Direction:** * AD is parallel to BC. * AB is parallel to DC. * AD is perpendicular to DC. * BC is perpendicular to DC (and CE is an extension of BC, so CE is also perpendicular to DC, implying angle DCE is a right angle). * Points A, F, E are collinear.
