Answer:

(1). m∠X'Z'Y'=90°

(2). m∠MCY=90°,

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

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.
