Point
What is the vocabulary term for when two rays share a common endpoint?
angle
A pair of lines that would never intersect
Parallel Lines
an enclosed figure with straight edges
Polygon
The number of unit squares needed to cover a region
Area
a straight path of points that is endless in both directions
line
An angle that measures exactly 90° and creates a square angle
right angle
Lines that intersect and form square angles (right angles)
Perpendicular Lines
a polygon with 4 sides and 4 angles
quadrilateral
What is the formula for Area?
A=l x w
part of a line that has 2 endpoints
line segment
An angle SMALLER than 90 degrees
Acute Angle
Perpendicular
A quadrilateral with at least one pair of parallel sides
Trapezopid
The distance around a figure
Perimeter
part of a line that has 1 endpoint and continues endlessly in the other direction
ray
An angle BIGGER than 90 degrees
Obtuse angle
pass through the same point but not possible for lines to intersect at more than one point
Not at a 90 degree angle, or perfect plus
Intersect Lines
Rhombus
a quadrilateral that contains four equal-length sides
used to measure area that measures 1 unit on all sides
Square Unit
A line that divides a figure into two parts with the same shape and size
Line of Symmetry
How many degrees is a straight line? What is the name of this angle?
180 degrees, straight angle
Give one example of intersect lines in the classroom
answers will depend
Why is a square never a rectangle?
A rectangle has four 90 degree angles but a square ALSO has 4 sides of equal length.
How are Area and Perimeter different?
Area multiples length and width, Perimeter adds all the sides
