The way to use the distance formula to classify quadrilateral include:
- Use the distance formula to measure the lengths of the sides.
- Use the slope to check whether the sides are perpendicular and form right angles.
- Use the slope to check whether the diagonals are perpendicular to each
<h3>How to illustrate the information?</h3>
The steps to calculate the perimeter and area of a polygon:
Step 1: Plot the given points on the graph.
Step 2: Connect the points and identify the figure.
Step 3: Determine lengths by counting the grid lines.
Step 4: Use a formula to calculate the perimeter and area if one exists.
Step 5: If there are no formulas for a figure, the perimeter can be calculated by summing the lengths of the sides. We might estimate the area without an area formula by counting the number of small squares enclosed.

The length of the other leg to the nearest tenth of a foot is 5.7 feet.
What is Pythagorean theorem?
- A theorem in geometry: the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
- The Pythagoras theorem equation is expressed as,
, where 'c' = hypotenuse of the right triangle and 'a' and 'b' are the other two legs.
We can use the Pythagorean Theorem to find the length of the other leg
"a" and "c" represent the two legs of the triangle and "b" represents the perpendicular.
So,
= 7² - 4²
b = 
⇒ 5.7 feet
Therefore, the length of the other leg to the nearest tenth of a foot is 5.7 feet.
