Polygons
Draw a polygon
Any 2D flat closed shape with at least 3 connecting lines
I have 4 congruent sides and 4 right angles. What quadrilateral am I?
A square
What does the term "congruent" mean?
Same size, same shape
Plot, connect, identify, explain
(3,1) (3,9) (7,7) (7,3)
Trapezoid
Is a rectangle? Explain why or why not.
No, it does not have all congruent sides
True or False: A circle is a type of polygon
False because it does not have straight lines
I have exactly one set of parallel sides. What quadrilateral am I?
Trapezoid
What does the term "quadrilateral" mean?
4 sides and 4 angles
Plot, connect, identify, explain
(3,2) (3,7) (8,7) (8,2)
Square
Is a square a rectangle? Explain why or why not
Yes, it has 2 sets of parallel sides and 4 right angles
True or False: All polygons have right angles
False, several polygons such as rhombus/triangles/trapezoids/hexagon/octagon do not have right angles.
I have 4 congruent sides. My angles may be obtuse, acute, and/or right. What quadrilateral am I?
Rhombus
Perpendicular lines form ___________________
right angles
Plot, connect, identify, explain
(5,3) (5,8) (8.8) (8,3)
Rectangle
Is a trapezoid a parallelogram? Explain why or why not
No, trapezoids have only one set of parallel sides
True or False: Quadrilaterals are polygons
True - They are flat, 2D, closed shapes with 3 or more connecting lines.
I have 2 sets of parallel sides. I might have right, acute, or obtuse angles. I might have congruent sides or a pair of congruent sides. What quadrilateral am I?
Parallelogram
An attribute describes a characteristic of a shape like color, size, # of ___________ and # of _______.
Sides/Angles
Plot, connect, identify, explain
(0,6) (2,8) (5,8) (4,6)
Parallelogram
Square, rectangle, parallelogram, rhombus, trapezoid. Which one does not fit in with the rest and why?
Trapezoid, it only have (1) set of parallel sides.
Roberto draws 2 quadrilaterals with opposite sides parallel and all sides equal. Which two did he draw?
Rhombus
Square
I have 2 sets of parallel sides. My opposite sides are congruent. I have 4 right angles. What quad am I?
Rectangle or Square
What does the term lateral mean?
Sides
Plot, find the missing vertex (have ordered pair ready) identify what you drew and explain
(2,7) (9,7) (9,4)
(2,4) Rectangle
True/False: It's possible to draw a trapezoid with two right angles, one obtuse angle, and one acute angle.
True, plot (1,1) (1, 5), (5,5) (9,1)
