WebA rectangle has two diagonals, they are equal in length and intersect in the middle. A diagonal's length is the square root of (a squared + b squared): Diagonal "d" = √ (a 2 + b 2) Example: A rectangle is 12 cm wide, and 5 cm tall, what is the length of a diagonal? d = √ (122 + 52) = √ (144 + 25) = √169 = 13 cm Golden Rectangle Webthe diagonals, shown as dashed lines above, meet at a right angle. one of the diagonals bisects (cuts equally in half) the other. ... and that's it for the special quadrilaterals. Irregular Quadrilaterals The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.

I want to do a quick argument, or proof, as to why the diagonals of a rhombus are perpendicular. So remember, a rhombus is just a parallelogram where all four sides are equal. In fact, if all four sides are equal, it has to be a parallelogram. And just to make things clear, some rhombuses are squares, but not all of them. iphone ios 確認方法
