So in this diagram, it is true that BC equals CD. I do not understand what this question is asking and how I should answer. If the shape is close to being a square but not exactly a square, it doesn't necessarily have any of the square properties. Suppose both pairs of opposite sides of a quadrilateral are parallel. It could be just two congruent right triangles attached at the hypotenuse, like this. Turns out that if even both facts together are true, that does not guarantee that the shape is a square. In word problems, be careful not to assume that a quadrilateral has parallel sides or equal sides unless that is stated. So this one does not guarantee the quadrilateral is a square. 0 0. Do not despair, though, because a few of them yield to area formulas, just as the square does. It could be just two congruent right triangles attached at the hypotenuse, like this. Question 7 options: has all right angles and has all sides congruent has all sides congruent and all angles congruent is a parallelogram with perpendicular diagonals is both a rectangle and a rhombus ... that does not guarantee that the shape is a square. In the last three of these methods, you first have to prove (or be given) that the quadrilateral is a rectangle, rhombus, or both: If a quadrilateral has four congruent sides and four right angles, then it’s a square […] Which description does NOT guarantee that a quadrilateral is a square?

A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Which statement does not guarantee that a quadrilateral is a square? a. is a parallelogram with perpendicular diagonals b. is both a rectangle and a rhombus c. has all sides congruent and all angles congruent d. has all right angles and has all sides congruent ____ 2. In fact, it's not any special quadrilateral at all. Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon, 5-sided polygon, and hexagon, 6-sided polygon), and 4-gon (in analogy to k-gons for arbitrary values of k).A quadrilateral with vertices , , and is sometimes denoted as .
