To graph: The given
Answer to Problem 7MCQ
Graph of the given figure and its image after given rotation is shown as under:
so that the vertices of its imaged triangle be G`(4,2),H`(-3,0) and J`(3,4)
Explanation of Solution
Given information: A triangle GHJ with vertices
Formula/Concept used: By rule, in rotation by 180 degree around the origin, the original vertex
And the coordinates of the point around which to be rotated, remains the same.
Calculation: Based on above rule, the corresponding vertices of the imaged figure will be:
And on plotting them in XY plane, the graph of image of given figure is shown as:
Conclusion: So, imaged triangle G`H`J` is larger than original triangle.
