Triangle ABC has vertices A(−2, 0), B(2, 5), C(3, 1). The reflection of the image of triangle ABC is triangle A'B' C' with vertices A'(−2, 0), B'(2, −5), C'(3, −1). What is a rule that describes the reflection?

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

the answer is:

mean: 6

mad: 2.14
