A geometric figure has an angle of the following measurements. Eighty 91 thirty 51 twelve sixty eight, which two angle measurements correspond to the supplementary pair list the measurements of smaller angle first and the measure of the larger angle second

The supplementary pair of angles is composed of two angles whose measures add up to 180 degrees.

Given measurements:
- Eighty: 80 degrees
- Ninety-one: 91 degrees
- Thirty: 30 degrees
- Fifty-one: 51 degrees
- Twelve: 12 degrees
- Sixty-eight: 68 degrees

To find the supplementary angles, we need to pair up two angles whose measures sum to 180 degrees.

Possible pairs of angles that add up to 180 degrees are:
1. Eighty (80 degrees) and One Hundred (100 degrees).
2. Thirty (30 degrees) and One Hundred Fifty (150 degrees).

Therefore, the two angle measurements corresponding to the supplementary pair are 80 degrees and 100 degrees, and 30 degrees and 150 degrees, respectively.
