Spiral Review #10 Coordinate Pl (6.MG.3) & Congruence (6.MG.4)

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 (x, y).

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: 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 distance between two points on a coordinate plane?

Back

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

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical halves that are mirror images of each other.

Front

What is the significance of the origin in a coordinate 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 points on the plane.

Front

What does it mean for two shapes to be congruent?

Back

Two shapes are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

How can you identify the quadrant of a point with negative x and positive y coordinates?

Back

A point with negative x and positive y coordinates is located in Quadrant II.

Front

What is the formula for finding the midpoint between two points?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the purpose of plotting points on a coordinate grid?

Back

Plotting points helps visualize relationships between variables and understand geometric concepts.

Front

How do you find the x-coordinate of a point in Quadrant I?

Back

In Quadrant I, the x-coordinate is always positive.
