Pentagon ABCDE is dilated according to the rule
Tema [17]
The coordinates of A in the pre-image is (-1,2).

D0, 3(x,y) means (x,y) → (3x,3y)

A'(-3,6)
B'(-0.5, 8)
C'(2,6)
D'(1,3)
E'(-2,3)

The coordinates of the pre-image are multiplied by 3 resulting to the coordinates of the given image. So, we simply divide each value of x and y by 3 to get the coordinates of the pre-image.

A'(-3,6) → -3/3 = -1 ; 6/3 = 2 → A(-1,2)

Which statement proves that △XYZ is an isosceles right triangle?
stepladder [879]
In order for the triangle to be called an isosceles right triangle, it must satisfy both conditions: XZ and XY must be perpendicular to each other, and XZ = XY.
To determine whether two lines are perpendicular, their slopes must be negative reciprocals of each other.

Solving for the slopes of XZ and XY:
slope of XZ = (y₂-y₁) / (x₂-x₁) = (6-3)/(5-1) = 3/4
slope of XY = (y₂-y₁) / (x₂-x₁) = (3--1)/(1-4) = -4/3
-4/3 is the negative reciprocal of 3/4, therefore XZ and XY are perpendicular to each other.

Solving for distance:
XZ = √[(y₂-y₁)²+(x₂-x₁)²] = √[(6-3)²+(5-1)²] = 5
XY = √[(y₂-y₁)²+(x₂-x₁)²] = √[(3--1)²+(1-4)²] = 5

<span>The slope of XZ is 3/4, the slope of XY is -4/3, and XZ = XY = 5. </span>
