WebAnd we see that they are. These two are kind of candidate alternate interior angles, and they are congruent. So AB must be parallel to CD. Actually, I'll just draw one arrow. AB is parallel to CD by alternate interior angles congruent of parallel lines. I'm just writing in some shorthand. Forgive the cryptic nature of it. I'm saying it out. WebStudent incorrectly drawing a parallelogram ; Opposite sides are not parallel or congruent.… Did you consider all properties of a parallelogram? Students may make incorrect inquiries concerning drawing parallelograms… Do all parallelograms have to be congruent? Students making incorrect assumptions concerning congruent …

WebQuadrilateral. A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees. The word quadrilateral is derived from the Latin words ‘Quadra’ which means four and ... as tartarugas marinhas
