Geometry, supplementary angles?

Question

Answer sometimes, always, or never.

If two angles are supplementary then one angle is acute and one angle is obtuse.

I'm confused xD

Answer 1

supplementary angles add up to 180degrees, making a straight line when placed next to each other. one would have to be obtuse(more than 90 degrees) and the other acute(less than 90 degrees). the only other option is for both to be exactly 90 degrees, and i can't remember if there's a rule about that.

Answer 2

Sometimes

Supplementary means they add up to 180 like

40, 140

72, 108

these are one obtuse, one acute

However 90,90 works too and these are right angles

Answer 3

It just means the degrees of 2 angles adds up to 180 degrees. Two 90 degree angles makes a straight line, an 80 degree and a 100 degree would make a straight line too. Any 2 angles that adds up to 180 degrees. GOOD LUCK DUDE!!!

Answer 4

First, you define what supplementary angles are.  Naturally, they're angles that sum up to 180 degrees.  Now let's observe obtuse and acute angles.  Of course, an obtuse and acute angle can add up to 180 degrees (120 and 60).  Now never is not the right choice.  Now let's see if this is always true.  What types of angles are there?  Generally, acute, right, and obtuse.  We've used obtuse and acute, but what about right?  180 degrees can be made up of two right or 90 degree angles.  So it isn't always true.  So the answer is sometimes.

Answer 5

Supplement angles add to 180 degrees.  Generally, one one angle is acute and one angle is obtuse.  But, you could have two at 90 degrees, which are right angles.

The answer is sometimes.

or

Always, except when they are right angles.
