23-24 Fall Semester Review OL

Front

What does it mean for points to be collinear?

Back

Points are collinear if they lie on the same straight line.

Front

What is the distance formula?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²), used to find the distance between two points (x1, y1) and (x2, y2).

Front

How do you find the median of a set of numbers?

Back

To find the median, arrange the numbers in order and identify the middle value. If there is an even number of values, average the two middle values.

Front

What is the measure of an angle if it is equal to another angle?

Back

If angle M measures 66 degrees, then angle Y also measures 66 degrees.

Front

What is the midpoint formula?

Back

The midpoint formula is M = ((x1 + x2)/2, (y1 + y2)/2), used to find the midpoint between two points (x1, y1) and (x2, y2).

Front

What are collinear points in a geometric figure?

Back

Collinear points are points that lie on the same straight line.

Front

How do you calculate the distance between two points with the same x-coordinate?

Back

If two points have the same x-coordinate, the distance is the absolute difference of their y-coordinates.

Front

What is the first step in finding the median of a data set?

Back

The first step is to arrange the data set in ascending order.

Front

If two angles are equal, what can be said about their measures?

Back

Their measures are the same.

Front

How do you find the coordinates of the midpoint between two points?

Back

Add the x-coordinates and divide by 2 for the x-coordinate of the midpoint, and do the same for the y-coordinates.
