6.11-Coordinate Plane-Lesson 13

Front

What is the coordinate plane?

Back

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

Front

What are the four quadrants of the coordinate plane?

Back

Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

How do you determine the quadrant of a point with negative coordinates?

Back

If both coordinates are negative (e.g., (-x, -y)), the point is located in Quadrant III.

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent the coordinates of a point on the coordinate plane.

Front

What does the x-coordinate represent?

Back

The x-coordinate indicates the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent?

Back

The y-coordinate indicates the vertical position of a point on the coordinate plane.

Front

How do you find the distance between two points on the coordinate plane?

Back

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

Front

What is the significance of integer coordinates?

Back

Integer coordinates are points on the coordinate plane where both x and y values are whole numbers.

Front

What is a right triangle?

Back

A triangle with one angle measuring 90 degrees.

Front

What is an isosceles triangle?

Back

A triangle with at least two sides of equal length.
