Using Pythagorean Theorem to Find the Distance Between Two Points

The video tutorial introduces the Pythagorean theorem and its application in finding distances in the coordinate plane. It explains how to form right triangles and calculate the hypotenuse using the theorem. The lesson includes example problems and student exercises to reinforce understanding. The tutorial concludes with a final example and a summary of the key concepts.

What is the primary objective of using the Pythagorean theorem in the coordinate plane?

• To find the area of a triangle

• To identify the midpoint of a segment

• To calculate the distance between two points

• To determine the slope of a line

Why are right triangles useful in the coordinate plane?

• They help in finding the area of polygons

• They simplify the process of graphing lines

• They allow for easy calculation of angles

• They enable the use of the Pythagorean theorem to find distances

In the example with points (1,2) and (5,5), what are the lengths of the triangle's legs?

• 5 and 6
