How many degrees are in a full circle?

360. A full circle represents a complete rotation, which is defined as 360 degrees. This is the standard measurement used for circular geometry.

Which tool is used to measure and draw angles?

Protractor. A protractor is a specialized tool designed to measure angles in degrees. You place the center of the protractor on the vertex to get an accurate reading.

What is the measure of a right angle?

90 degrees. A right angle measures exactly 90 degrees and forms a perfect square corner. It is a fundamental building block in geometry and construction.

An angle that measures less than 90 degrees is called what?

Acute. An acute angle is defined as any angle that measures less than 90 degrees. The word 'acute' often implies something sharp or small.

What is an angle called if it measures more than 90 but less than 180 degrees?

Obtuse. An obtuse angle is larger than a right angle (90 degrees) but smaller than a straight angle (180 degrees). It appears wide and open.

What is the measure of a straight angle?

180 degrees. A straight angle measures exactly 180 degrees. It looks like a single straight line because the two rays point in opposite directions from the vertex.

What do we call two angles that add up to 90 degrees?

Complementary. Complementary angles are pairs of angles whose measures sum to exactly 90 degrees. They often fit together to form a right angle.

What do we call two angles that add up to 180 degrees?

Supplementary. Supplementary angles are pairs of angles that combine to equal 180 degrees. If placed side-by-side, they form a straight line.

What kind of angle measures between 180 and 360 degrees?

Reflex. A reflex angle is an angle that is greater than 180 degrees but less than 360 degrees. It represents the larger rotation between two rays.
