Coordinate Grid Flashcard

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs.

Front

What is an ordered pair?

Back

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

Front

What does the x-coordinate represent?

Back

The x-coordinate represents the horizontal position of a point on the coordinate grid.

Front

What does the y-coordinate represent?

Back

The y-coordinate represents the vertical position of a point on the coordinate grid.

Front

What is a vertex in geometry?

Back

A vertex is a point where two or more lines meet, often used to describe the corners of shapes like squares and polygons.

Front

How do you identify a point to the right of a line on a coordinate grid?

Back

A point is to the right of a line if its x-coordinate is greater than the x-coordinate of the line at the same y-coordinate.

Front

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

Back

The origin is the point (0, 0) on a coordinate grid where the x-axis and y-axis intersect, serving as the reference point for all other points.

Front

How can you determine if a point is inside a shape on a coordinate grid?

Back

A point is inside a shape if it lies within the boundaries defined by the vertices of the shape.

Front

What is a hexagon?

Back

A hexagon is a six-sided polygon, which can be regular (all sides and angles are equal) or irregular.

Front

What does it mean for a point to be outside the perimeter of a shape?

Back

A point is outside the perimeter of a shape if it does not lie within the boundaries defined by the vertices of the shape.
