Stacey drew a triangle on a coordinate plane. She wrote down the ordered pair for each vertex. How many ordered pairs did she wrote down?
Hmmmm. Three vertexes...
yeah - a regular vortex of vertices . . .
To determine the number of ordered pairs for a triangle, we need to know the number of vertices in the triangle. A triangle has three vertices, so Stacey would have written down three ordered pairs.
In a coordinate plane, an ordered pair represents a point. Each ordered pair consists of two numbers enclosed in parentheses, (x, y), where x represents the x-coordinate and y represents the y-coordinate.
Thus, Stacey would have written down three ordered pairs, one for each vertex of the triangle.
