2D Shapes
A quadrilateral with 4 equal sides and 4 right angles.
A square!
What is a quadrilateral?
A polygon with four sides, four angles, and four vertices.
An angle that is less that 90 degrees is called an....
acute angle
Which direction is the x axis?
Horizontal
A quadrilateral in which one pair of sides is parallel and one is not.
Trapezoid
What are vertices?
A point where 2 or more line segments meet, a corner.
An angle that is equal to 90 degrees is called a....
right angle
Does the y axis run vertical or horizontal?
Vertical
A 6 sided polygon with 6 angles and 6 vertices
Hexagon
Two lines that intersect and create a 90 degree angle.
An angle that is greater than 90 degrees is called an....
obtuse angle
What is an ordered pair?
2 numbers used to show the X and Y values on a graph
A quadrilateral with 2 pairs of parallel sides, the pairs are not necessarily equal.
A rectangle. One set of parallel sides is longer than the other.
What is a coordinate plane?
A flat plane that has an X and Y axis.
This is two lines that intersect to form a right (90 degree) angle.
Perpendicular Lines
How do I label my ordered pair on a coordinate plane?
I place a point on the plane to show the location.
A closed, 2D shape with straight sides.
A polygon
What is a degree?
This is two lines that NEVER intersect.
Parallel Lines
What is an origin?
It is where the X and Y axis intersect, with the ordered pair of (0,0).
