A and B are two points on square ABCD with coordinates A(1,3) and B(5,3). What are the lengths of the diagonals AC and BD? Round
lilavasa [31]

Answer:

AC = BD = 5.7

Step-by-step explanation:

Given

A = (1,3)

B = (5,3)

Required

The length of the diagonals

First, calculate the length of AB using:

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}

So, we have:

AB = \sqrt{(1 - 5)^2 + (3 - 3)^2}

AB = \sqrt{(-4)^2 + 0^2}

AB = \sqrt{16}

AB = 4

The diagonal of a square is calculated using:

Diagonal = x\sqrt{2

Where x is the length of each side.

So:

AC = BD = AB\sqrt{2}

AC = BD = 4\sqrt{2}

AC = BD = 5.7 -- approximated

On a piece of paper, use a protractor and a ruler to construct two equilateral triangles: one with a side length of 4 inches and
sergiy2304 [10]

Answer:

the two triangles are the same shape but not the same size

Step-by-step explanation:

an equilateral triangle has all equal sides. if one triangle has a side length of 4 inches, it'll be smaller than the triangle with the side length of 5 inches but just because they're different sizes doesn't mean they're a different shape. (i don't know if this is right but I'm pretty sure it is)
