We first talked about what is angles and how looks like them and we learned how to solve the some of there.like the rertically opposite or parallel lines and angles how to solve the transvensal then we learned about enlargments and reduction whoch means multiplied or divide .when we want solve them we should have two triangles or maybe the question should talk about two triangles but in there the angles not changing just the triangle make bigger without change their angles .in those two angles we have two things that actually called image abd original one of them should be original and the other one is a image that means the image should be bigger or smaller than original and in a questions we need got how much that image got bigger or smaller and thatj called scale factor .scale factor= length in the image__ lenght in the original original . Scale factor = image

The Butterfly

When we are doing the butter fly theory we should have four number in a two fraction and between them should be a equal then one of them should be a X or a number we did’nt figure out what it is.then we can find it with givin help from our bring
