The answer is C,

Coterminal when involving angles is an angle that is 360 degrees greater or lesser. In order to find whether something is coterminal or not you take one of your angles and subtract or add 360 from it until you reach that number. If you add/sub 360 and you can't ever equal the other number than they are not coterminal.

Example:

591 - 360 = 231
So that means
231 degrees = 591 degrees

Example 2:

51 - 360 = 309

51 + 360 = 411

411 + 360 = 771

771, 411, and 309 /= 591 or 231

So 51 degrees /= 231 or 591

C: 51 is not coterminal!

Explain why segments connecting any pair of corresponding vertices of congruent pentagons are congruent. make a sketch to suppor

Veronika [31]

Answer:

Congruence between pentagons

Step-by-step explanation:

The relationship occurs because having two congruent Pentagons and generating a segment within them (or outside), congruence is extrapolated to the triangles generated within them. Thus, if there is congruence among the pentagons, it will exist between the formed triangles. In other words since the two pentagons are congruent, the corresponding angle pair is congruent. also the two corresponding side pairs are also congruent.

In the attached image for example, the ABCDE and KLMNO pentagons are congruent, so all of their internal division lines are also congruent (AC and KM)
