Question

A right 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

Answer 1

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.
