Calculate the distances between two points using the distance formula.
The ancient Greeks used sundials to measure time by tracking the position of the sun.
Here, we are using a tree as a sundial. Drag the sun on the slider to cast shadows at
different times of the evening. Use the Pythagorean theorem to find the length of the
Adjust the triangle to find the straight-line distance. Drag the blue point horizontally and the red point vertically to the entrance point of the destination.
A group of firefighters must extend their ladder to douse a fire 15 meters up on the fourth floor of a building. There is a fire hydrant in their way, so they need to place the base of the ladder further away from the building. Move the red point to determine the distance from the edge of the building to the closest point that will work.
Quinn and Anna want to find the direct distance between their houses. They plot their houses on a grid, and plan to draw a right triangle and then use the side length distances to calculate the hypotenuse. Use their method to find the distances between their houses.
Create a right triangle by moving the red dot until the red angle becomes a right angle.
Solves the length of a segment on the coordinate plane using the distance formula.
