all right boys and girls so we are going to start talking about our shape so we're on lesson 15-1 which is Page 859 all right it says draw some clothes shapes that have 3 vertices that means three corners okay if I have one 2 the ring I'm going to connect my vertice when am I going to end up with what is the name for your shape triangle right and it's the same for every shape even if I did it like this like this or like this I would still have three corners and it's still considered a triangle pain now we're going to match the shape to its name Hazel triangles has 3 sides 3 vertices quadrilaterals have four sides and four vertices Pentagon always have 5 sides and 5 vertices hexagon always has 6 sides and 6 vertices K and you're a look at each one you're going to see that they're not that okay this is not a quadrilateral quadrilaterals are flat plane Pentagon flat plane shapes all right they always have four sides are always and they always have the same season same number of sides if they have as vertices in plane shapes okay so match each shape to its name here i c y 234 so I know it's a quadrilateral here and see one two three four five six so that is a hexagon 1 2 3 4 5 6 Pentagon 1 2 3 triangle hey now you're a look at the shape and tell how many sides and vertices and the name of it so I have a 1 2 3 4 four sides and four vertices that would make it a quadrille lateral paint here I see one two three four five five one two three four five vertices that is a 29 Kenny So based on the sides and vertices you can tell the name write 5/10 means 5 so that's why has 5 sides and 5 vertices next page all right you weren't the same thing match each shape to its name so i c 1 2 3 4 quadrilateral Miss Kay Louis I got distracted by that notification all right I have one two three four right 1 2 3 4 5 Pentagon 1 2 3 4 six hexagons 1 2 3 triangle 1 2 3 4 quadrilateral ic3 triangle by Pentagon for quadrilateral fix hexagon one tooth 3456 k draw the shape tell how many sides and vertices quadrilateral have 4 so 1 2 3 4 hexagon has 6 1 2 3 4 5 6 triangle has three one two three and that's that Bianca drew a triangle in a pentagon how many sides and vertices did she draw in all you're a triangle and a pentagon so running to one two three four five so she has three what's 5 + 8 + 8 right hey h Marcos has for toothpicks he places them as shown what shape can Marcos make as one more toothache so let's say he added one more here to close the shade so you have 1 2 3 4 5 which should make it a pentagon remember the shape have to be closed in order for it to be a more polygons can I connect all the dots to make two shapes that have vertices and name the shape that makes 1 2 3 4 5 6 letter hexagon 1 2 3 rainbow Randall said that a square is a quadrilateral Susan said that a square is a square that is not a quadrilateral who is okay so Randall is correct and we got to think about this he's correct because a square is a type of quadrilateral right now not every quadrilateral is a square a rectangle angle can also is also a quadrilateral cuz it also has four sides right so not every Square sorry every square is a quadrilateral but not every quadrilateral is a square all right to think that in your head so he's right because it's where does have four sides and four vertices right and but so does a rectangle and the last one which polygon is not a hexagon 1 2 3 4 5 6 that one is 1 2 3 4 5 6 7 8 1 2 3 4 5 1 2 3 4 5 6 o z
