Calculating Triangle Area Concepts

This video tutorial explains how to calculate the area of a triangle given its three vertices. It begins with graphing the triangle and assigning coordinates to each vertex. The instructor then introduces the formula for calculating the area and demonstrates its application using the given coordinates. The process involves simplifying the expression to arrive at the final area value. The video concludes with a summary and information on additional resources available on the instructor's channel.

What is the first step in calculating the area of a triangle given its vertices?

• Calculate the perimeter

• Graph the triangle

• Find the midpoint of each side

• Determine the type of triangle

Which of the following is a correct coordinate for vertex A?

• (0, 0)

• (6, -4)

• (3, 5)

• (-3, -2)

What is the formula used to calculate the area of a triangle given its vertices?

• base * height

• x1 + y1 + x2 + y2 + x3 + y3

• 1/2 * |x1(y2-y3) + x2(y3-y1) + x3(y1-y2)|

• 1/2 * base * height
