rotate figure efgh 180° around the origin.
rotate figure efgh 180° around the origin.
Answer
Explanation:
Step1: Find coordinates of original points
Assume each grid is 5 units. Point (E=(10,20)), (F=(20,20)), (H=(10,10)), (G=(20,10))
Step2: Apply 180 - degree rotation formula
The formula for a (180^{\circ}) rotation about the origin is ((x,y)\to(-x,-y)) For point (E(10,20)): ((10,20)\to(- 10,-20)) For point (F(20,20)): ((20,20)\to(-20,-20)) For point (H(10,10)): ((10,10)\to(-10,-10)) For point (G(20,10)): ((20,10)\to(-20,-10))
Answer:
The new coordinates of the rotated figure are (E'(-10,-20)), (F'(-20,-20)), (H'(-10,-10)), (G'(-20,-10))
