Math Problem Statement

find the area of the triangle

find the area of the triangle

Solution

To find the area of the triangle, we first need to determine the coordinates of the triangle's vertices from the graph.

The triangle appears to have the following vertices:

  • G(4,4)G(4, 4)
  • H(0,8)H(0, 8)
  • F(6,6)F(-6, 6)

The area AA of a triangle with vertices (x1,y1)(x_1, y_1), (x2,y2)(x_2, y_2), and (x3,y3)(x_3, y_3) is given by the formula:

A=12x1(y2y3)+x2(y3y1)+x3(y1y2)A = \frac{1}{2} \left| x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2) \right|

Let me calculate the area for this triangle.The area of the triangle is 16square units16 \, \text{square units}.

Would you like any further details or explanations on this? Here are 5 related questions you might find interesting:

  1. How would you calculate the perimeter of this triangle?
  2. Can you explain why the formula for the area of a triangle works?
  3. What would happen to the area if one of the vertices was moved to a new location?
  4. How can you check if the given points are collinear?
  5. How do you determine if a triangle is a right triangle using its vertices?

Tip: When working with triangles on a coordinate plane, always label the vertices clearly and use the formula carefully to avoid mistakes.
