Right Triangle Concepts and Calculations

The video tutorial explains how to plot points on a coordinate plane, focusing on labeling points as X and Y. It demonstrates identifying the coordinates of a right triangle and connecting these points to form the triangle. The tutorial then uses the Pythagorean theorem to calculate the hypotenuse, explaining each step in detail. The final conclusion confirms the hypotenuse length as five units.

What is the best practice when labeling points on a coordinate plane?

• Label them as 1 and 2

• Label them as A and B

• Label them as Y and X

• Label them as X and Y

Which of the following is a correct set of coordinates for a right triangle on a coordinate plane?

• (0, 0), (4, 0), (0, 3)

• (0, 0), (3, 0), (0, 4)

• (0, 0), (2, 2), (3, 3)

• (0, 0), (3, 3), (4, 4)

What is the first step in forming a right triangle on a coordinate plane?

• Calculate the hypotenuse

• Label the points

• Determine the area

• Connect the points

Which formula is used to calculate the hypotenuse of a right triangle?

• a² - b² = c²

• a + b = c²

• a² + b² = c²

• a² + b² = c
