Example Question #11 : Similarity Transformations Given Two Figures: Ccss.Math.Content.Hsg Srt.A.2
Which of the other triangles is similar to ?
None of the answers.
This is the correct answer because it has similar angles, and if we do some simple math, we can figure out what the missing angle is in the original picture.
Adding the two know angles and recalling that all interior angles of a triangle have a sum of 180 degrees, the following equation is constructed.
Now solve for B, to figure out what the missing angle is.
Now if we look at the missing angle in the picture, it has the same angles.
The other pictures don't have similar answers.
