Question

tiove, william m.g.q1 benchmark #1 (25 - 26) 15 of 20 if triangle abc is rotated 90 degrees clockwise about the origin, what are the coordinates of b? (4,1) (1,4) (-4, -1) (1, -4)

Explanation:

Step1: Identify original coordinates of B

From the graph, the coordinates of point B are (-1, 4).

Step2: Apply 90 - degree clock - wise rotation rule

The rule for a 90 - degree clockwise rotation about the origin is $(x,y)\to(y, - x)$. For point B with coordinates (-1, 4), substituting $x=-1$ and $y = 4$ into the rule, we get $(4,1)$.

Answer:

(4, 1)
