Question

How do you use coordinate geometry to find relationships within triangles?

Answer 1

Answer:

Coordinates will show the vertices of the triangle, and using the vertices, calculate length of the sides of the triangle. With the side length you can now calculate the angles of the triangle.

Step-by-step explanation:

The coordinates of the triangle can be plotted on a graph tool to give you the exact shape.Then using the coordinates that represent vertices for the triangle, apply the distance formula; d = √(y2 − y1)² + (x2 − x1)²

This gives the length of the sides of the triangle. With the side length values, youcan apply the cosine rule : c²-a²+b²-2ab cos c to find the angles in the triangle.
