There are two rectangles what are the ratio of the first to the second?
I guess you mean the ratio of the areas; it depends if the 2 rectangles are "similar figures"; that is their matching sides are in the same ratio. If they are similar then the ratio of their areas is the square of the ratio of the sides.
How can you tell whether two polygons are similar?
Polygons will be similar if they have the same number of sides AND all of their angles are the same. All of their angles are the same if all but one of their angles are the same because with the same number of sides the angles must add up to the same thing. All squares are similar (4 right angles and sides of equal lenght). All rectangles are similar (4 right angles). We know two triangle are similar if two or mare angles are the same, or if one angle is the same and the two adjacent sides are the same length. Variations of this last proof may apply to some other polygons.
How many rectangles are in a 5 by 4 grid?
Oh, dude, you're really making me count rectangles now? Ok, fine. So, in a 5 by 4 grid, you've got 15 horizontal lines and 10 vertical lines, which means you've got 15 x 10 = 150 rectangles. But hey, who's counting, right?
How many rectangles can be drawn with 38 cm as the perimeter?
There would be an infinite number of rectangles possible
Are all rectangles congruent Explain your answer?
yes, all rectangles are in fact congruent. they're all congruent because its a ratio of sizes. if u have a rectangle with a length of 5 and a width of 2.5, and an another rectangle with a length of 10 and a width of 5, u have a ratio of sixes. the ratio would be 1:2. hope it helps (:
Are all rectangles never similar?
No, not all rectangles are similar because the proportions are different.
Are all golden rectangles similar?
yes all golden rectangles are simalar as well as their ratios
Are two rectangles always similar?
Two rectangles are seldom but sometimes similar. They can be but they don't have to.
How do you know if two rectangles are similar?
Two rectangles are similar if corresponding angles are equal and the corresponding sides are proportional.

How are rectangles and trapezoids similar?
how are trapezoids and rectangles
What rectangles are similar to a 10 by 15?
All rectangles which have sides in the ratio 10:15 would be similar. This would include 2 x 3, 4 x 6, 100 x 150, etc. Note that similarity in rectangles is very simple, since all interior angles are by definition right angles.
Are some rectangles similar?
no some rectangles cannot be similar. a rectangle is a shape with 2 = sides and then 2 more different = sides. it is impossible because if 2 rectangles were similar than that would not be a rectangle. similar means having corresponding sides no it is not possible
Are all rectangles are similar true or false?
false. you can have a 3 by 5 or a 8 by 29
Aside from the vertex the horizontal cross-sectional shapes of this pyramid are all similar rectangles?
True
Are all squares rectangles but not all rectangles squares?
Yes, all Squares are rectangles, but not all rectangles are squares because it needs to have all equal sides.
Are all rectangles parallelagrams?
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
