The rows and columns of lattice points in a three-by-three square array are evenly spaced one unit apart. How many distinct triangles with at least one side of length 2 units can be drawn using three lattice points for the vertices?

Write each expression in exponential form and find its value. 3 x 3 x 3

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

What dimensions can créate more than one triangle ?
