Flash Coordinates Flashcard

Front

What is a coordinate in a Cartesian plane?

Back

A coordinate is a set of values that show an exact position. In a 2D Cartesian plane, it is represented as (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does the x-coordinate represent in a point (x, y)?

Back

The x-coordinate represents the horizontal position of the point on the Cartesian plane.

Front

What does the y-coordinate represent in a point (x, y)?

Back

The y-coordinate represents the vertical position of the point on the Cartesian plane.

Front

How do you identify the y-coordinate from a point?

Back

The y-coordinate is the second number in the ordered pair (x, y). For example, in (1, 2), the y-coordinate is 2.

Front

What is the formula to calculate the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = Length x Width.

Front

What are the properties of a rectangle?

Back

A rectangle has opposite sides that are equal in length and all angles are right angles (90 degrees).

Front

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

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect. It serves as the reference point for all other coordinates.

Front

How do you plot a point on a Cartesian plane?

Back

To plot a point (x, y), start at the origin, move 'x' units along the x-axis, and then 'y' units up or down along the y-axis.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they never intersect and are always the same distance apart.

Front

What is the difference between adjacent sides and opposite sides in a rectangle?

Back

Adjacent sides are the sides that meet at a corner, while opposite sides are the sides that are across from each other.
