Polygons
Draw and name a shape with 3 sides
triangle
What are these lines called?
_______________
_______________
Parallel
draw a right angle (put a square in the angle)
L
what are the 3 types of transformations
1. translation (slide)
2. reflection (flip)
3. rotation (turn)
3 features of polygons
1. Sides
2. Vertices
3. Angles
draw and name a shape with 4 sides
quadrilateral
Show me what Perpendicular lines look like AND what makes them special?
+
Can you draw an angle less than 90 degrees? Can you name it for extra points?
Acute angle
draw a translation (don't forget your point of rotation)
Slide
3 properties of polygons
1. straight sides
2. 2D Shape
3. must be closed
draw and name a shape with 5 sides
pentagon
Show me what intersecting lines look like. What makes them different from perpendicular lines?
(Draw on whiteboard)
- Intersecting lines DO NOT make right angles
Can you draw an angle greater than 90 degrees? Can you name it for extra points?
Obtuse angle
draw a reflection (don't forget your point of rotation)
flip
I will make 2 groups of shapes you have to come up with the sorting rules for them (there are many correct answers)
.
draw and name a shape with 6 sides
hexagon
how many sets of parallel lines does this shape have (paralellogram)
2 sets
Draw a shape with 4 right angles. Can you name it for extra points
quadrilateral
draw a rotation (don't forget your point of rotation)
turn
What is the difference between an irregular shape and a regular shape? Can you draw one shape for each.
A regular shape has equal sides.
An irregular shape has sides with different lengths
draw and name a shape with 8 sides
octagon
Name the 3 different types of lines we have learned and show me the matching arm movements.
1. parallel =
2. perpendicular +
3. Intersecting
Can you name a shape with an obtuse angle, or can you name a shape with an acute angle? Do both for extra points
obtuse angle = pentagon, hexagon, octagon
acute angle = triangle
Draw the translation, rotation, and reflection of a shape of Miss. Shaw's choice. (don't forget your point of rotation)
...
True or false: A trapezoid and a parallelogram are both regular quadrilaterals. Can you draw them for extra points?
false
