Chapter 4 Pretest

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), used to locate points using ordered pairs (x, y).

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height.

Front

How do you find the height of a parallelogram if you know the area and the base?

Back

Height = Area ÷ base.

Front

What are the coordinates of a point?

Back

Coordinates are a pair of numbers (x, y) that define the position of a point on a coordinate plane.

Front

What is a vertex in geometry?

Back

A vertex is a point where two or more lines or edges meet.

Front

What is the distance between two points on a coordinate plane?

Back

The distance can be calculated using the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is a square?

Back

A square is a quadrilateral with four equal sides and four right angles.

Front

How do you determine if four points form a parallelogram?

Back

Check if the midpoints of the diagonals are the same or if opposite sides are equal and parallel.

Front

What is the significance of the x-axis and y-axis in a coordinate plane?

Back

The x-axis is the horizontal line, and the y-axis is the vertical line; together they help locate points in a two-dimensional space.

Front

What does it mean for two points to lie on the same vertical line?

Back

Two points lie on the same vertical line if they have the same x-coordinate.
