Quadrilaterals Types of Parallelograms

today we are learning how to classify different types of parallelograms now parallelograms are type of quadrilateral and they look like this they have two sets of sides that are parallel to each other but there are actually many different types of parallelograms sometimes parallelogram can be called rhombus or sometimes rectangle now rhombus looks like this it's parallelogram it has two sets of parallel sides but in addition all of the sides are the same length we can show that by putting one of these dashed lines on each side so that's rhombus what about rectangle well rectangle looks like this it's parallelogram it has one two sets of parallel sides but what makes rectangle special are its angles rectangles have four right angles which will be shown with these square angle signs in each corner and so that's rectangle but believe it or not there's actually one more type of parallelogram if you combine both rhombus and rectangle you end up with square square looks like this it's parallelogram it has all sides being the same length we'll use those dashes to show it and it has four right angles will use those square angle signs to show that now there's also one more type of parallelogram it's this one we first looked at it's parallelogram because it has one two sets of parallel sides but its side lengths are not the same and it doesn't have any right angles so this doesn't have any of these special names we can only call this shape parallelogram and here you have it these are all of the possible names for parallelograms let's practice this together let's identify what type of shape is this well how many sets of parallel sides does this shape have you can see this shape has two sets of parallel sides here and here now does this shape have any right angles no there are no right angles on this shape what the side lengths or the side lengths the same yes you can see every side in this shape is the same length all the sides are the same length so what type of shape is this when you have two sets of parallel sides and all sides are the same length you have rhombus here's another problem to practice with what type of shape is this well how many sets of parallel sides does this shape have this shape has two sets of parallel sides here and here does this shape have right angles no this shape has no right angles and are all of the side lengths are the same no you can see that the sides are different lengths so this only has two sets of parallel sides what can we call this shape remember when shape only has two sets of parallel sides it's just called parallelogram now it's time for you to practice on your own what type of shape is this well this shape has one two sets of parallel sides it also has four right angles that means this is rectangle here's your last problem for this video what type of shape is this this shape has two sets of parallel sides here and here it has four right angles and all of the sides are equal lengths that means this shape is square today you learned how to identify different types of parallelograms
