Understanding Right Triangles and Area Calculation

This video tutorial explains how to find the area of a triangle by identifying it as a right triangle. The instructor demonstrates how to prove the right angle by calculating the slopes of the triangle's sides and showing they are opposite reciprocals. Once the right angle is confirmed, the base and height are identified, and the area is calculated using the formula 1/2 base times height, resulting in an area of 25 square units.

What are the given side lengths of the triangle discussed in the video?

• 3 and 4

• 7 and 9

• 5 and 10

• 6 and 8
