Is it possible for supplementary angles to also be equal angles? Be sure to use proper mathematical terminology. Include numbers, pictures and/or words in your explanation.

No, supplementary angles cannot also be equal angles. Supplementary angles are two angles that add up to 180 degrees. If we have two angles that are equal, let's say 60 degrees each, they cannot be supplementary because 60 + 60 equals 120, which is not equal to 180.

In mathematical terms, if angle A and angle B are supplementary, then angle A + angle B = 180. However, if the angles are equal, then angle A = angle B, and the sum of these angles will be 2 times angle A or 2 times angle B, which is not equal to 180.

Here is a visual representation to illustrate this:

```

In the diagram, two equal angles A and B are shown. If we try to combine them to form a supplementary angle, the sum of A and B will not equal 180 degrees. Therefore, supplementary angles cannot also be equal angles.
