The perimeter of a square is 4 times as great as the lenth of any of its sides determine if the perimeter of a square is proport
Leokris [45]
Let; x = side length
perimeter = 4x

since it's a square, with equal sides, the perimeter will always be proportional to it's side length. increase the side, increases the perimeter.

proportional: two quantities having the same constant ratio or relation. The quantities x and y are proportional if:
y/x = k
where k is the constant of proportionality.

4x/x = 4
k = 4

Estimate the sum of 23 and 71
Natali [406]
Estimation:

23 --> rounded to 20
71 --> rounded to 70
70 + 20 = 90. I rounded both numbers down so the exact sum must be only a little greater than my estimate.

Which would prove that △ABC ~ △XYZ? Check all that apply.
satela [25.4K]

Answer:

Correct options,

a) \frac{BA}{YX}=\frac{BC}{YZ}=\frac{AC}{XZ}

c) \frac{AC}{XZ}=\frac{BA}{YX} and ∠A = ∠X

Step-by-step explanation:

 Given : ΔABC ≅ Δ XYZ

We have choose out of given options that correctly prove that ΔABC ≅ Δ XYZ

 

Two triangles are said to be similar when their corresponding  sides are in same ratio and the measure of their corresponding angles are equal.

That is \frac{AB}{YX}=\frac{BC}{YZ}=\frac{AC}{XZ}

and ∠ A = ∠X , ∠ B = ∠Y AND ∠C = ∠Z

Also ,

We have conditions for two triangle to be similar.

1) SSS : When the ratio of all the three sides of a triangle are equal.

that is \frac{AB}{YX}=\frac{BC}{YZ}=\frac{AC}{XZ}

2) SAS: When the ratio of two corresponding sides are equal and the measure of angle between those sides are equal

\frac{AB}{YX}=\frac{AC}{XZ} and ∠ A = ∠X

Thus, Out of given options,

a) \frac{BA}{YX}=\frac{BC}{YZ}=\frac{AC}{XZ}

c) \frac{AC}{XZ}=\frac{BA}{YX} and ∠A = ∠X
