## What is the symbol for midpoint?

NOTE: The midpoint of line segment AC denoted by the symbol overline {AC} is located at point B. This implies that line segment AB, written as overline {AB}, and line segment BC, written also as overline {BC}, have equal measure.

## How do you write a midpoint answer?

Correct answer: The formula for midpoint = (x_{1} + x_{2})/2, (y_{1} + y_{2})/2. Substituting in the two x coordinates and two y coordinates from the endpoints, we get (–1 + 3)/2. (4 + 6)/2 or (1, 5) as the midpoint.

## What is the midpoint of 10 and 15?

the difference between 10 and 15 is 5. 5 midpoint is 2.5.

## What is the midpoint of AB?

To answer what the midpoint of AB is simply replace the values in the formula to find the coordinates of the midpoint. In this case these are (2 + 4) / 2 = 3 and (6 + 18) / 2 = 12. So (x_{M}, y_{M}) = (3, 12) is the midpoint of the segment defined by A and B.

## How do you find the midpoint of a line example?

Midpoint of a Line Segment

- Add both “x” coordinates, divide by 2.
- Add both “y” coordinates, divide by 2.

## What is a symmetry line?

A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly. Equally, if you were to place a mirror along the line, the shape would remain unchanged. A square has 4 lines of symmetry, as shown below.

## How do you write a ray?

A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).
