Quadrants and Reflections

Front

What is a quadrant in a coordinate plane?

Back

A quadrant is one of the four sections of a coordinate plane, divided by the x-axis and y-axis.

Front

How many quadrants are there in a coordinate plane?

Back

There are four quadrants in a coordinate plane.

Front

What are the coordinates of a point in the first quadrant?

Back

In the first quadrant, both x and y coordinates are positive.

Front

What are the coordinates of a point in the second quadrant?

Back

In the second quadrant, x coordinates are negative and y coordinates are positive.

Front

What are the coordinates of a point in the third quadrant?

Back

In the third quadrant, both x and y coordinates are negative.

Front

What are the coordinates of a point in the fourth quadrant?

Back

In the fourth quadrant, x coordinates are positive and y coordinates are negative.

Front

What is reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the reflection of a point across the x-axis?

Back

The reflection of a point (x, y) across the x-axis is (x, -y).

Front

What is the reflection of a point across the y-axis?

Back

The reflection of a point (x, y) across the y-axis is (-x, y).

Front

If a point is reflected across the y-axis, what happens to its x-coordinate?

Back

The x-coordinate changes sign.
