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).

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).

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.

What is congruence in geometry?

Back

Congruence means that two shapes are identical in shape and size, but may be oriented differently.

Front

How do you identify the quadrant of a point?

Back

Look at the signs of the x and y coordinates: (+, +) for Quadrant I, (-, +) for Quadrant II, (-, -) for Quadrant III, and (+, -) for Quadrant IV.

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

Back

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

Front

What does it mean for two shapes to be similar?

Back

Two shapes are similar if they have the same shape but may differ in size, meaning their corresponding angles are equal and their sides are proportional.

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, serving as the reference point for all other points.

How can you tell if a shape has rotational symmetry?

Back

A shape has rotational symmetry if it can be rotated around a central point and still look the same at certain angles.
