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?
To calculate the number of rectangles in a 5 by 4 grid, you can use the formula for the number of rectangles in an n by m grid, which is n*(n+1)m(m+1)/4. Plugging in the values for n=5 and m=4, you get 5*(5+1)4(4+1)/4 = 564*5/4 = 600/4 = 150 rectangles. So, there are a total of 150 rectangles in a 5 by 4 grid.
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 (:
How do you work out the area of a compound shape?
wht u hve to do is to cut the shape into rectangles and then times the length and width together on each rectangle. then add up all the rectangles areas and add them alll up. ta da
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 all squares and rectangles similar?
All squares are rectangles, as they meet the definition of having four right angles and opposite sides that are equal in length. However, not all rectangles are similar to each other; similarity requires that corresponding angles are equal and corresponding side lengths are proportional. Since rectangles can have different side lengths, they are not necessarily similar unless they have the same aspect ratio. In contrast, all squares are similar to each other because they have equal sides and angles.
Are two rectangles always similar?
Two rectangles are seldom but sometimes similar. They can be but they don't have to.
Are two rectangles always sometimes or never similar?
Two rectangles are always similar. Similarity in geometry means that two shapes have the same shape but may differ in size. Since rectangles have the same angles (all right angles) and their corresponding sides are in proportion, any two rectangles can be considered similar regardless of their dimensions.
Which pair of rectangles contains similar polygons?
To determine which pair of rectangles contains similar polygons, you need to check if their corresponding angles are equal and their sides are proportional. Rectangles are inherently similar to each other since all angles are 90 degrees and the lengths of sides can vary while maintaining the ratio. Thus, any pair of rectangles will contain similar polygons, as they share the same shape but can differ in size.
How do you know if two rectangles are similar?
Two rectangles are similar if corresponding angles are equal and the corresponding sides are proportional.
what is the lateral faces of a rectangular prism?
They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 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.
How are rectangles and trapezoids similar?
how are trapezoids and rectangles
Aside from the vertex the horizontal cross-sectional shapes of this pyramid are all similar rectangles?
True
Are all rectangles are similar true or false?
false. you can have a 3 by 5 or a 8 by 29
