Question

1)Write the equation of the line that contains the
__
altitude of (triangle)RST from T to RS.

2) If a translation is done on (triangle) RST such that point S is moved to coordinates of point R, then the new coordinates for point R will be?

3)If (triangle) RST is reflected through the x-axis, what will be the new coordinates for point T?

Answer 1

to translate, just imagine moving the whole triangle. the translation coordinate is as follows: (0,1) - (-4,7) = (4,-6) therefore to find the new point T, just add the previous coordinates of T with the translation coordinate, getting: (8,1)
They new points are now called RXY, assuming.

part b, reflecting through x axis, since T is perpendicular to x axis ( parallel to y axis), the x coordinates remain the same. also, since T is 7 units in the direction of Y away from x axis, the reflected image of T would be 7 units in the negative Y direction, and the new coordinate is now (4,-7)

thankx for explaining! :)
