Ho do you prove the formula for the area of a rectangle?
Use squares and try it out for yourself. Get a number of squares and make a rectangle 3 squares long by 4 squares wide. Count the squares. You should have 12 squares (or 3*4). That's the best way I know to prove the formula.
What shape is always similar?
Squares and circles are always similar.
The AA Similarity Postulate states that two triangles are similar if they have?
You would use the AA Similarity Postulate to prove that the following two triangles are similar. True or false?
Why can't you use AAA to prove two triangles congruent?
You can't use AAA to prove two triangles congruent because triangles can have the same measures of all its angles but be bigger or smaller, AAA could probably be used to prove two triangles are similar not congruent.
How does transformations prove that two triangles are similar?
By enlargement on the Cartesian plane and that their 3 interior angles will remain the same
Are two squares always similar?
yes.
Is two squares always sometimes or never similar?
Yes
What will always be similar a two different squares b two different rectangles c two different rhombuses d two different parallelograms?
a) two different squares
What is similar about a perfect square trinomial and a difference of two squares?
Each has two binomial factors.
How can you use ratios of adjacent sides to prove if two rectangles are similar?
You can use ratios of adjacent sides to prove if two rectangles are similar by comparing to see if the ratios are the same
Are two squares always the same?
Yes and No, all squares will have the same internal angels (90 degrees) making them similar, but dimensions of squares can be different (how long the sides are).

How can you tell both shapes are similar?
to prove two triangles are similar, get 2 angles congruent
Are all squares similar to quadrilaterals?
All squares are quadrilaterals. Not all quadrilaterals are squares.
Two squares are similar The ratio of a set of sides is 2 and 4 What is the ratio of their areas?
1:2
Are all squares the same?
yes all squares are extremely similar
Are all squares similar?
Yes, all squares are similar because they are all in proportion. The angles will always be 90 degrees, and the sides proportionate. The same ratio can be created using any two side measures between squares. Thus, all squares are similar.
