- A quadrilateral is a polygon that has 4 sides.
- Slide 4
- One way that you can classify quadrilaterals is by the position of their sides, side length, and angle measure.
- Slide 5
- A parallelogram is a quadrilateral where opposite sides are parallel (hence, the name) and congruent. This is a more general term for a quadrilateral. PARALLELOGRAM
- Slide 6
- The following shapes are all specifically named parallelograms.
- Slide 7
- A rhombus is a quadrilateral with 4 congruent sides. A rhombus is a type of parallelogram. PARALLELOGRAM RHOMBUS Notice the similarities between the parallelogram and the rhombus. Although a parallelogram may look very similar to a rhombus, remember the key to being a rhombus is the congruent sides.
- Slide 8
- A rectangle is another type of parallelogram. A rectangle is a parallelogram that also incorporates 4 right angles. PARALLELOGRAM Although the rectangle shown may not look much like the parallelogram, a rectangle is still a parallelogram. Remember that a parallelogram only has to have opposite parallel and congruent sides. A rectangle fits that description, so hence, it is a parallelogram. RECTANGLE
- Slide 9
- A square is a very special quadrilateral, since it incorporates the features of a parallelogram, rhombus, and rectangle all in one little shape. Notice the similarities between the shapes. PARALLELOGRAM RHOMBUS RECTANGLE SQUARE
- Slide 10
- Is a square really a quadrilateral, parallelogram, rhombus, and a rectangle? Lets find out!
- Slide 11
- A quadrilateral is a polygon with 4 sides. Does a Square fit that description? Yes, a square fits that description! SQUARE A square is a polygon And it has 4 sides
- Slide 12
- A parallelogram is a quadrilateral where opposite sides are parallel and congruent. Does a Square fit that description? Yes, a square fits that description perfectly. SQUARE These two opposite sides are parallel and congruent... And so are these two sides!
- Slide 13
- A rhombus is a quadrilateral with 4 congruent sides. A rhombus is a type of parallelogram. Does a Square fit that description? Yes, a square fits that description perfectly also. SQUARE We already know that a square is a parallelogram. And all the sides are congruent
- Slide 14
- A rectangle is a parallelogram that incorporates 4 right angles. Does a Square fit that description? Yes, a square fits that description perfectly also. SQUARE We already know that a square is a parallelogram. And all the angles are right angles (90)
- Slide 15
- As we just saw, a square is indeed a Quadrilateral Parallelogram Rhombus and Rectangle ALL IN ONE!
- Slide 16
- But there are quadrilaterals that arent parallelograms. Next, well look at those
- Slide 17
- A trapezoid is a quadrilateral that has ONLY 1 pair of parallel sides. Unlike the other quadrilaterals, a trapezoid isnt a parallelogram. Its just a trapezoid and, of course, a quadrilateral. TRAPEZOID
- Slide 18
- A trapezium is quadrilateral with no pairs of parallel sides. A TYPE OF TRAPEZIUM
- Slide 19
- Identify this shape with all of its possible names.
