hello boys and girls this week our lesson is 32 classify quadrilateral shape that has 4 sides four angles are standard for this week is recognized rhombuses rectangles and squares are quadrilaterals and then draw examples of quadrilaterals that do not look at your vocabulary attribute we had last week you should know that it is any characteristic of an object or a shape parallels are always the same distance apart are the same distance apart railroad tracks the same distance a parallelogram is a quadrilateral because it has four sides but the opposite sides are parallel and equal in length then we have quadrilateral two dimensional shape with four sides and four angles now look at the bottom you see a rhombus and you see a rectangle think about those two shapes for a minute okay which one of these are do they have four sides and four angles 45123 4 okay rectangle 1 2 3 4 5 1 2 3 4 angles does a rhombus and a rectangle okay look at them okay which shape has two pairs of sides that are the same length so that's one pan inside and this side are the same length it's a rectangle top and bottom or the same so that's one pair left side right side of the same so that's two pair of parallel rhombus two pair of parallel sides which of these shapes or do both states have four sides is a rhombus all four sides are the same length the top and bottom of the same length but they're not the same as the left and the right side how much is the only shape in out of these two that has four sides are the same length Okay now which of these two would have four square corners if you look at the wrong but you seen no square corners we have acute angles here so these are not square look at your rectangle you have a square corner here Square square and square so all four corners of the rectangle or square a quadrilateral is in shape with four sides and four angles okay you have may have to look closely at a little start here but these are quadrilaterals we have a parallel you have a rectangle and a rhombus they are both parallelograms your square is a parallelogram okay a trapezoid is a trapezoid and isosceles trapezoid and a kite are quadrilaterals because they have four sides and four angles okay so a quadrilateral we know is a parallelogram if it has two pair of parallel sides and two pairs of sides the same length triangle your rhombus and your square and you will find the two pair of parallel sides and two side to side two pair of sides the same length a quadrilateral is a rectangle yeah it has four square corners that we just saw that four square corners it also has two pair of parallel sides and two pair of sides the same length a quadrilateral is a rhombus yeah it has two pair of parallel sides and four sides that are the same length now think about it is a square a square is a quadrilateral but how can we or how can you explain that to someone what makes it a quadrilateral Square two pair of parallel sides your top and bottom and your left and right side and it also have two parents to sign late because of a square have all the same length we're going to compare some quadrilaterals first we're going to look at the square and we're going to look at the rectangle okay is a square a rectangle is a rectangle a square in order for it to be a square a rectangle must have all the attributes of a square A square has four sides and four angles a rectangle also has four sides and four angles four square corners or Square and rectangle have Square corner two pair of parallel sides your top and bottom and left and right are parallels so there's two pair of parallel sides in a square and the two pair of sides the same length of your top and bottom and sides are the same length and four sides the same length and here's where they differ your Square Tab 4 sides the same length of rectangle only has four sides the same length sometimes so every what is a rectangle chart you see that every square is a rectangle but not every rectangle is a square every square is a rectangle but not every rectangle is a square because it only has four sides with the same length sometimes okay now let's look at this next one is a square a rhombus is a rhombus a square here we have square we know it has four topping for Angel has four square corners it has two pair of parallel sides two pairs of sides the same length and four sides the same now let's go down to the rhombus does it have four sides and four angles yes does it have four square corners sometimes but not always does it have two pair of parallel sides two pair of sides the same length yes all four sides the same length yes so if we look it up that every Square is a rhombus but not the only time a rhombus will be asked where is if it has to square corners okay let's look at that it is also a quadrilateral because one two three and it has four angles 1 2 3 4 sides and 4 angles so it is no parallel sides are the same distance apart but that means the same thing would be there touching so they are not parallel do that doesn't have any square corners have two pair of to tear the same length does it we have to hear and to hear is face shape of quadrilateral yes because it has four sides and four angles does a quadrilateral a parallelogram have the same length a rectangle four square corners and Tupac so it is not a rectangle shape of square no because it does not have any square corners a parallelogram is a rectangle a quadrilateral and a square is a quadrilateral now you should be able to complete Pages 342 and 345 in your instruction book and then complete your problem solving pages and you have pages 357-2364 so you should have completed all the pages up to 364 in your problem-solving book at the end of this week
