### What kind of angles are Two angles on one side of a straight line?

If the two angles sum adds up to 180 degrees, then they are supplementary angles.

### An angle whose measures have a sum of 180 degrees?

a straight line or supplementary angles...which equal to 180 degrees.

### What does Euclid's 5th postulate say?

If a straight line falling on two straight linesmakes the interior angles on the same side of it taken together less than two right angles , then the two straight lines , if produced indefinitely , meet on that side on which the sum of angles is less than two right angles.

### How many angles are there in a straight line?

straight line indicates 180o

### Can two angles whose sum is a straight angle be acute?

If you mean a 180o angle, which is represented as a straight line, then no. Two acute angles cannot add up to 180o because an acute angle is less than 90o.

### How can you use the fact that the sum of the angles on a straight line is 180 to explain why the angle at a point are 360?

Draw any straight line through the point. The sum of the angles at the point are the sums of the angles on each side of the line - which are known to be 180o. Thus: the sum of the angles at the point = the sum of the angles of each side of the line = 180o + 180o = 360o The sum of the a
