How to Create a Right Triangle in the Coordinate Plane

In this Math Test Prep video, the instructor guides students through solving a standardized math test question involving the creation of a right triangle on a coordinate plane. Wendy plots points J and K, and the task is to determine the location of point L to form a right triangle. The instructor explains the properties of right triangles and demonstrates plotting four potential locations for point L. After testing each option, the correct answer is identified as point C (2, 4), which successfully forms a right triangle with points J and K.

What is the main task Wendy needs to accomplish with points J, K, and L?

• Create an equilateral triangle

• Form a right triangle

• Draw a line segment

• Plot a square

Which of the following is a characteristic of a right triangle?

• All angles are 60 degrees

• It has one 90-degree angle

• All sides are equal

• It has two 90-degree angles

What are the coordinates of the first answer choice plotted?

• (4, 2)

• (-7, 1)

• (-1, 7)

• (2, 4)

Which point, when plotted, successfully forms a right triangle with points J and K?

• (4, 2)

• (2, 4)

• (-7, 1)

• (-1, 7)

What was the final step taken to confirm the correct location of point L?

• Changing the coordinate plane

• Flipping the triangle

• Replotting all points

• Using a protractor
