Atriangle is reflected across the line x=2. which of the following is true? a. the image and pre-image have the same orientation. b. the image and pre-image have different sizes. c. the image and pre-image are congruent. d. the image and pre-image are separated by a given angle.

C

Step-by-step explanation:

C. the image and pre-image are congruent.  

Step-by-step explanation:

a triangle is reflected across the line x=2

Check with each option

A. the image and pre-image have the same orientation.

The image will not be in same order

B. the image and pre-image have different sizes. the size will not change

C. the image and pre-image are congruent. the reflection will not change the size. so they are congruent

D. the image and pre-image are separated by a given angle.

The angles never change in reflection

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
