Select the following statement that is true about shape a and shape b. Question 12 options: Similar—shape b has been stretched, but all its angles have the same measure, so these shapes must be similar. Similar—shape b has been dilated, so the shapes are similar but not congruent. Not similar—shape b has been stretched, these shapes are neither similar nor congruent. Not similar—though you can obtain shape a from shape b, you cannot obtain shape b from shape a.
