How do you use 9 toothpicks to form 5 triangles?
Make a triangle, each of whose sides is 2 matchsticks long. This uses six matchsticks. Join the middle points of the sides of this triangle to one another - using another three match sticks. You will then have four small triangles and one large one.
Are rectangles always similar to each other?
Similar shapes need to have the same number of sides, the same angles and the ratio of the sides needs to be the same. Rectangles are not always similar to each other because they can have different dimensions, which would break the "same ratio" rule.
Can you call a 4 sided shape a parallellogram?
Only if 2 sides are parallel with each other, and the other two sides are also parallel with each other. All squares are rectangles. All rectangles are parallelograms. All parallelograms are 4 sided. But not all 4-sided are parallelograms, not all parallelograms are rectangles, and not all rectangles are squares.
How many faces of a triangular prism are made up of rectangles?
Three. There are three rectangles that are joined along their parallel edges which forms a triangle at each end.
How many right angles are there in two squares and two rectangles?
16 - four in each !
How many different rectangles can be drawn using the hours of a clock as each rectangle vertices?
12
How do you play poker with matchsticks?
Generally this means playing poker with matchsticks as chips. So each player would start with the same number of matchsticks and bet with them as if they were chips.
How many rectangles can be made using 24 tiles?
To determine the number of rectangles that can be made using 24 tiles, we need to consider the different possible dimensions of rectangles. A rectangle can have a length and width ranging from 1 to 24, inclusive. Each unique combination of length and width will form a distinct rectangle, so the total number of rectangles can be calculated by summing the total number of combinations for each possible length and width. This can be done using the formula n(n+1)/2 for the sum of the first n natural numbers, where n is the total number of tiles (24 in this case).
How do you find the area of an L shape?
Assuming you have the dimensions of each of the sides - treat it as two separate rectangles. Using the measurements you have, work out the areas of both rectangles - then add them together.
How do you figure the square footage of a home?
Model each floor of the house with one or more rectangles, compute the area of each of these rectangles, and sum them to the total square footage. If the shape of you house if really complicated you may have to throw a triangle in there, but most houses can be approximated well enough using rectangles.
How are rectangular prisms and cubes different?
Cubes have a square on each side, but rectangular prisms have rectangles or squares.
How many different rectangles can you form using 24 centimeter squares?
It depends on whether rotations are considered the same or different. 1 x 24, 2 x 12, 3 x 8, 4 x 6 are the distinct rectangles if rotations are disallowed. Each of them can be rotated through 90 degrees to give four more if rotated versions are considered different.

Why are not all parallelograms rectangles why?
Rectangles include 4 angles of 90 degrees each
What is the rectangles?
A rectangle is a 2D shape that has 2 sides and 2 ends of different lengths, with a right-angle in each corner.
What number is made by 30 matchsticks?
30 110000000 4 sticks in each 0 and one in 1
