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 distance between two points is:

`D = sqrt( (X_1 - X_2)^2 + (Y_1 -Y_2)^2)`

where:

- D is the distance 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.
