We can tell if the components on each side of the equation are congruent when you see the equals sign with a squiggly line on top. Name the corresponding sides after that. Two triangles with corresponding sides have matching sides. Congruent triangles will have the same length.
How did you recognize the triangles' matching sides?The same two angle pairs are touched by corresponding sides. When the sides are equivalent, you can multiply each side by the same value to move from one triangle to another. The corresponding sides of the triangles in the similar triangles diagram are the same color.The side a (next to b) must match either v or x, for instance, if one polygon has the sequential sides a, b, c, d, and e and the other has the sequential sides v, w, x, y, and z. (both adjacent to w).If two triangles have sides A,B,C and a,b,c, respectively, and they are similar, then the pair of matching sides are proportionate, meaning that A: a = B: b = C.The relationship between the sides and angles of two congruent triangles is referred to as "corresponding parts of congruent triangles," or cpct.To learn more about Triangles refer to:

What is arithmetic sequences?Arithmetic sequences take the following format: a, a+d, a+2d, a+3d, etc. up to n terms. A is the first term; d is a frequent difference; and n is the total number of terms.
Find the AP, the number of terms, and the common difference for the calculation using the arithmetic sequence formulas. To determine the nth term, sum, or common difference of a given arithmetic sequence, various arithmetic series formulas are used.
To find the lengths of the first four segments we use the Arithmetic progression formula that is
[tex]a_n =[/tex] a₁ + (n - 1)d
Where
an = the nᵗʰ term in the sequence
a₁ = the first term in the sequence
d = the common difference between terms
We have a₁ as 5 cm and as it is being duplicated the common ration d is 5
and we have been asked the length of the first four segments, so n = 4
Lets substitute the given information

a list on integers has a mode of 32, mean 22 and median m. m iiis one of the numbers on the list.
nvm this isnt the full quesion
The most appropriate choice for mean, median and mode will be given by-
Value of m = 20
What is mean, median and mode?
Mean of a data set gives the average value of the data set
Mean is calculated by the dividing sum of all observations by the number of observations.
Median is the middle value of the data set when the data set is arranged in ascending or descending order
Mode is the value of the data set which has the highest frequency
Here,
Let the number of integers be n
mean = 22
Sum = 22 x n
= 22n
Now m is replaced by m + 10
New sum = 22n + 10
New mean = 24
New sum = 24n
By the problem,
22n + 10 = 24n
24n - 22n = 10
2n = 10
n = [tex]\frac{10}{2}[/tex]
n = 5
Now mode of 5 numbers = 32
Smallest number = 10
Data set = {10, x, m, 32, 32}
Now , if m is replaced by m - 8, the new median is m - 4
Since 5 is odd, m - 4 is a member of this data set
So x = m-4 (As m- 8 < m - 4, so on replacing m by m-8 will shift m - 8 to second place and x to third place as the data set is arranged in ascending order)
Data set = {10, m-4, m, 32, 32}
Mean = [tex]\frac{10+(m-4)+m+32+32}{5}[/tex]
[tex]22 = \frac{70 + 2m}{5}\\70 + 2m = 22 \times 5\\70 + 2m = 110\\2m = 110 - 70\\2m = 40\\m = \frac{40}{2}\\m = 20[/tex]

[tex]$2^{5}[/tex] = 2 2 2 2 2 2 = 32. Power is defined as a base number multiplied by its exponent, where the base number is the factor multiplied by itself and the exponent is the number of times the same base number is multiplied.
What is meant by second power?The number 5³ is pronounced as "five to the third power," "five to the power three," or "five to the third." There are two special powers: "to the second power" is commonly pronounced "squared," and "to the third power" is commonly pronounced "cubed."To find ax, simply multiply a by itself x times. To compute two to the second power, multiply two by itself two times. The exponent of a number indicates how many times the number should be multiplied. The "2" in 8² tells us to multiply 8 twice, so 8² = 8 × 8 = 64. In other words, 8² could be referred to as "8 to the power 2," "8 to the second power," or simply "8 squared."To learn more about exponent, refer to:
