It is still 30\textdegree, no matter how you turn it hope this helps.
Answer:
The correct option is B.
Step-by-step explanation:
Given information: Triangle BCD is rotated 80° clockwise about the origin to form ΔKLM and ∠KLM = 30°.
Rotation is a rigid transformation, it means the size and shape or image and preimage are same.
Triangle BCD is rotated 80° clockwise about the origin to form ΔKLM. It means both triangles are congruent.
[tex]\triangle BCD\cong \triangle KLM[/tex]
The corresponding parts of congruent triangles are congruent, so
[tex]\angle BCD\cong \angle KLM[/tex] (CPCTC)
[tex]\angle BCD\cong 30^{\circ}[/tex]
[tex]\angle BCD=30^{\circ}[/tex]
The measure of angle BCD is 30°. Therefore the correct option is B.
