Following a translation, the measures of the angles in a pre-image

Following a translation the measure of angles of image are same as measure of angles in the pre-image.

Step-by-step explanation:

Since in a translation transformation the figure is just translated by some units either upward or downward or shifted to left or right.

But there is no change in the size or shape of the figure; hence the angle measures are also preserved.

Hence, following a translation the measures of the angles in a pre-image are congruent to the measure of angles in the image.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
