Front

What is a heptagon?

Back

A heptagon is a polygon with 7 sides and 7 angles.

Front

What are coordinates?

Back

Coordinates are a set of values that show an exact position on a graph, usually represented as (x, y).

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented as (0, 0).

Front

What is the x-coordinate?

Back

The x-coordinate is the first number in an ordered pair that indicates the horizontal position on a graph.

Front

What is the y-coordinate?

Back

The y-coordinate is the second number in an ordered pair that indicates the vertical position on a graph.

Front

What is the formula for finding the sum of interior angles of a polygon?

Back

The sum of interior angles of a polygon can be found using the formula (n - 2) × 180°, where n is the number of sides.
