Following transformations on Triangle ABC will result in the Triangle A'B'C'
a) Reflection the triangle across x-axis b) Shift towards Right by 2 units c) Shift upwards by 6 units
In Triangle ABC, the coordinates of the vertices are: A (1,9) B (3, 12) C (4, 4)
In Triangle A'B'C, the coordinates of the vertices are: A' (3, -3) B' (5, -6) C' (6, 2)
First consider point A of Triangle ABC. Coordinate of A are (1, 9). If we reflect it across x-axis the coordinate of new point will be (1, -9). Moving it 2 units to right will result in the point (3, -9). Moving it 6 units up will result in the point (3,-3) which are the coordinates of point A'.
Coordinates of B are (3,12). Reflecting it across x-axis, we get the new point (3, -12). Moving 2 units towards right, the point is translated to (5, -12). Moving 6 units up we get the point (5, -6), which are the coordinate of B'.
The same way C is translated to C'.
Thus the set of transformations applied on ABC to get A'B'C' are: a) Reflection the triangle across x-axis b) Shift towards Right by 2 units c) Shift upwards by 6 units
