Question

Figure ABCDE is the result of a 180° rotation of Figure LMNOP about the point. Which angle in the pre-image corresponds to ∠B in the image? Enter your answer in the box.

Figure L M N O P is rotated 180 degrees about a point resulting in image A B C D E.

Answer 1

Answer: ∠M in the pre-image corresponds to ∠B in the image.

Explanation:

When we look at the figures , we can see that the three vertices B , C , D are one side as vertices to M , N ,O .

Clearly , vertex C corresponds to vertex N ( presents in the middle )

Also, point B is at the right from point C .

In Figure L M N O P , vertex M is at the right from vertex N .

Thus , vertex M corresponds the vertex B.

It means ∠M in the pre-image corresponds to ∠B in the image.

Answer 2

Angle B in ABC DE is equal to angle M in LMNOP
