Question

Please tell me all about Dilation's, Similar triangles, Similar Polygons, Dilation's as Functions, and Scale Factors.

Answer 1

My teacher has to talk with me over the phone over these subjects particularly.

Answer 2

PLEASE NO DRAWING OR ANY LINKS. And thank you.

Answer 3

Similar figures have the same shape. Similar triangles will have all 3 corresponding angles equal. Same for similar polygons

Answer 4

OK

Answer 5

Dilations are when for example a small triangles sides are increased proportionally to give a large triangle. If we have a scale factor of 2 then each of its 3 sides will be twice as long as the smaller ones sides.

Answer 6

Cool anything else? I need to know?

Answer 13

I am not to good at congruent figures and congruencey in general. Can you help. Just type the basics and all I should know for the teacher I am calling.

Answer 15

Two figures are congruent if they are exactly the same : in shape and in size. I think in the US you also say 2 lines are congruent if they have same length. ( We just say they are equal in UK). When proving 2 things are congruent ( eg 2 triangles) you do not have to prove that all angles and all sides are equal but only certain combinations of angles and sides . For example if 2 sides and included angle are equal that is enough to prove congruency. This is abbreviated to SAS. Another example is SSS ( 3 sides equal) and AAS ( 2 angles and corresponding side).
