Which statements must be true about ru reflection of xyz across mn? select 3 options

BZ congruent to BZ'

XY congruent to X'Y'

X'Z'Y' 90 degrees

Step-by-step explanation:

(1). m∠X'Z'Y'=90°

(2). m∠MCY=90°,

(3). Line segment  BZ'≅ line segment BZ

Step-by-step explanation:

Line MN is reflecting line for ΔXYZ.  Triangle X'Y'Z'  is formed after reflection of ΔXYZ about a line MN. Therefore the line MN works like a symmetric axis of the given figure.

Hence

(1). m∠X'Z'Y'=90°, because ∠XYZ=90° and figure are symmetric about line MN.

(2). m∠MCY=90°, because figure is symmetric ,so line segment YY'⊥ line MN.

(3). Line BZ' ≅line BZ, because figure is symmetric about  about symmetric axis line MN and Line BZ'= line BZ.

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !
