The **Distance Between Two Points ** calculator computes the linear distance between two points in a plane.

**INSTRUCTIONS:** Enter the following:

- (
**X**) This is the X and Y values for point 1 (e.g. 3.3 5.6)_{1}, Y_{1} - (
**X**) This is the X and Y values for point 2. (e.g. 7.9 2.3)_{2}, Y_{2}

**Distance between Points (D):** The calculator returns the distance between the points. It assumes the units for the distance are the same units for the output.

The formula for the mid-point between two points is:

`MP = ( (X_1 - X_2)/2 , (Y_1 - Y_2)/2 )`

where:

- MP is the mid-point between the two points.
- X
_{1}is the x coordinate of point 1 - X
_{2}is the x coordinate of point 2 - Y
_{1}is the y coordinate of point 1 - Y
_{2}is the y coordinate of point 2

A **triangle** is a polygon with three sides, three vertices (corners), and three angles. **Triangles **can be classified based on the lengths of their sides and the measures of their angles as follows:

By Side Lengths:

**Equilateral Triangle**: All three sides are equal in length.**Isosceles Triangle**: Two sides are equal in length.**Scalene Triangle**: All three sides have different lengths.

By Angle Measures:

**Acute Triangle**: All three angles are less than 90 degrees.**Right Triangle**: One angle is exactly 90 degrees.**Obtuse Triangle**: One angle is greater than 90 degrees.

The sum of the interior angles of any triangle always adds up to 180 degrees.
