Aright triangle with angles measuring 45,45,and90 undergoes a reflection ,rotation, and translation determine whether the angle measure of the image of the triangle are 45,45,and90 after each translation

The measure of each angle remains the same after each transformation. The reason is because when you undergo a reflection, a rotation, or a translation, the triangle remains the same size and shape (congruent), therefore there is no change to the angles. The only thing changing is the position of the shape.

C. expression because any expression or equation may contain more than one variable
