What is an acute angle?
An angle that measures less than 90 degrees.
What is an obtuse angle?
An angle that measures more than 90 degrees but less than 180 degrees.
What is a right angle?
An angle that measures exactly 90 degrees.
What is a straight angle?
An angle that measures exactly 180 degrees.
What is a reflex angle?
An angle that measures more than 180 degrees but less than 360 degrees.
True or False: Two angles that are supplementary add up to 180 degrees.
True.
True or False: Vertical angles are always equal.
True.
What are adjacent angles?
Angles that share a common vertex and a common side but do not overlap.
What are complementary angles?
Two angles that add up to 90 degrees.
What type of angles are formed when two lines intersect?
Vertical angles and adjacent angles.
Fill in the blank: Angles that are on opposite sides of a transversal and outside the two lines are called __________ angles.
Alternate exterior angles.
Fill in the blank: Angles that are on the same side of the transversal and inside the two lines are called __________ angles.
Same-side interior angles.
What is a transversal?
A line that intersects two or more lines at distinct points.
What do you call angles that are in the same position on the two lines cut by a transversal?
Corresponding angles.
What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?
They are equal.
True or False: Corresponding angles are always supplementary.
False.
What is the sum of angles around a point?
360 degrees.
What type of angle measures exactly 270 degrees?
A reflex angle.
Fill in the blank: If two angles are complementary and one angle measures 30 degrees, the other angle measures __________ degrees.
60.
What is the measure of each angle in a pair of vertical angles?
They are equal.
What is the term for angles that sum up to 360 degrees?
Explementary angles.
What type of angles are formed by a straight line?
Straight angles (180 degrees).
True or False: Two angles are supplementary if one angle is acute.
True, if the other angle is obtuse.
What are the angles called that are formed inside parallel lines cut by a transversal?
Interior angles.
