Concave quadrilaterals: In concave quadrilaterals, one interior angle is greater than 180°. A quadrilateral is called a concave quadrilateral if at least one diagonal, i.e. the line segment joining the vertices is not a part of the same region of the quadrilateral.Convex quadrilaterals: In c...

A quadrangle is a general term for a four-sided figure, typically referring to an enclosed area or courtyard, while a quadrilateral is a specific geometric term for any four-sided polygon, including squares, rectangles, and trapezoids.
C下面的格子四边形围成的面积是多少?将点分配给四个顶点中的每一个,并用鞋带定理求出面积.让左下角(0,0),计数框,点(4,0),(0,5),(3,4),和(10,10).运用鞋带定理,∴x_1=1/2_21/2+1/1√(10)=1/2(20+30)(15|40+40)|=1/2|5095|=221/2.故选C.把皮克定理应用到图上,你会得到221/2...
