Coordinate Plane Practice Test REDO

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: 1st Quadrant (x > 0, y > 0), 2nd Quadrant (x < 0, y > 0), 3rd Quadrant (x < 0, y < 0), 4th Quadrant (x > 0, y < 0).

Front

How do you plot a point on a coordinate plane?

Back

To plot a point (x, y), start at the origin (0, 0). Move x units horizontally (right for positive, left for negative), then move y units vertically (up for positive, down for negative).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What is the distance from a point to the x-axis?

Back

The distance from a point (x, y) to the x-axis is the absolute value of the y-coordinate, |y|.

Front

What is the distance from a point to the y-axis?

Back

The distance from a point (x, y) to the y-axis is the absolute value of the x-coordinate, |x|.

Front

What are the coordinates of the origin?

Back

The coordinates of the origin are (0, 0).

Front

What does it mean for a triangle to be isosceles?

Back

An isosceles triangle has at least two sides that are of equal length.

Front

How do you identify the third vertex of an isosceles triangle given two vertices?

Back

To find the third vertex, ensure it is equidistant from the two given vertices.

Front

What is the significance of the x-axis and y-axis?

Back

The x-axis is the horizontal line on a coordinate plane, while the y-axis is the vertical line. They divide the plane into four quadrants.
