A shape is any plane figure with side and/or vertices.
A quadrilateral is a four-sided figure whose internal angles are 360 degrees.
A square is a quadrilateral that has four equal sides and four equal angles. The diagonals of a square bisect each other and the opposite sides of the square are parallel.
A rectangle is a four-sided shape where the opposite sides are parallel and of equal length. The diagonals of the rectangle also bisect each other.
A parallelogram is a quadrilateral where both pairs of opposite sides are equal. Its opposite sides and angles are congruent. Each diagonal of a parallelogram separates into two congruent triangles. A parallelogram is a convex polygon (interior angles less than 180 degrees.)
A rhombus has four equal sides, the diagonals of the square are perpendicular and bisect the opposite angles. Its vertices are not 90 degrees. The rhombus is not a cyclic quadrilateral (vertices lie on a single circle.)
PROPERTIES OF QUADRILATERALS:
1. Opposite sides are equal.
2. Opposite sides are parallel.
3. Opposite angles are equal.
4. Sum of two adjacent angles is 180 degrees.
5. Diagonals bisect each other.
I think you did well on your blog and it was structured very well
ReplyDeleteHi Francine! I like that you put images on each shapes and I like that you put properties of Quadrilaterals. Nice Work!
ReplyDeleteYou did well, I like the image locations and the way you structured your blog.
ReplyDeleteI like the structure of your blog Francine. The information is easy to understand
ReplyDeletenice work good job
ReplyDeletelooks like you did everything good nice job!
