what happens to the measure of the angles when a triangle is dilated the angle measure becomes larger the angle measure double if the scale factor is greater than 1 the angle measures become smaller the angle measures stay the same

The angle measures stay the same.
Reason: a dilation (uniform scaling) multiplies all distances by the scale factor but preserves angles, so the image is similar to the original triangle. (Even if the scale factor > 1 or < 1, angles are unchanged. Non‑uniform scaling with different factors in different directions is not a dilation and can change angles.)
