Graphing Polygons

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point on a graph, written in the form (x, y), where x is the horizontal coordinate and y is the vertical coordinate.

Front

What are the coordinates of point A if A is located at (5,2)?

Back

The coordinates of point A are 5 on the x-axis and 2 on the y-axis.

Front

What is the X-axis?

Back

The X-axis is the horizontal line on a graph where the y-coordinate is zero.

Front

What is the Y-axis?

Back

The Y-axis is the vertical line on a graph where the x-coordinate is zero.

Front

How do you find the missing vertex of a rectangle if you know three vertices?

Back

To find the missing vertex, use the coordinates of the known vertices to determine the x and y values that complete the rectangle.

Front

What is the formula for finding the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²).

Front

If a rectangle has vertices at (5,2), (5,-7), and (-5,-7), what is the fourth vertex?

Back

The fourth vertex D is located at (-5,2).

Front

What does it mean for points to be vertices of a polygon?

Back

Vertices are the corner points of a polygon where two sides meet.

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point (0,0) where the X-axis and Y-axis intersect.

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments.
