PLEASE HELP 1. How do you dilate a figure on the coordinate plane and determine its scale factor?
2. How do you determine if polygons are similar?
3. Explain one way can you determine if two triangles are similar, without knowing all the angle
or side measurements.?

1. You can look at side measurements. Angle measurements will not change so do not use them as reference. For example, if a rectangle has one side as 7 and the other 3, then the scale factor of a rectangle with a side of 21 and 9 would be 3, because 21÷7 is 3 or 9÷3 is 3.

2. You can determine a polygon is similar by having the same angles and/or similar sides.

3. All you need is one side and one angle if the angle and side are opposit each other, so a and A or b and B or c and C. If this is not represented in a problem then you can use 2 angles and 1 side or 1 angle and 2 sides to figure out if they are similar.
