When we reflect a point across y=x, the x and y coordinates switch out , that is (x,y) becomes (y,x) . SO for point (1,2), on reflection across y=x, (1,2) becomes (2,1) . And when we do reflection across y=-x, (x,y) becomes (-y,-x). Therefore point (2,1) on reflection across y=-x becomes(-1,-2) .
So the final answer is (-1,-2) .
To estimate the volume of Thai triangular prism you will use the formula for finding the volume.
V=Bh, where B is the area of the base and h is the height of the prism.
V = (1/2 x 12.6 x 1.6) x 10.75
V = 108.36 cubic mm
You answer is approximately 108 cubic millimeters.
