InfGeo Vertical Angles & Linear Pairs & Some Review

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles whose non-common sides form a straight line, summing to 180 degrees.

Front

What is the relationship between vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect, and they are always equal.

Front

How do you find the value of x in angle problems?

Back

To find the value of x, set up an equation based on the relationships between the angles (e.g., complementary, supplementary, or vertical angles) and solve for x.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

What is a complementary angle?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is a supplementary angle?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

If RM = 3 and MS = 3, what is the total length of segment RS?

Back

The total length of segment RS is RM + MS = 3 + 3 = 6.

Front

How do you determine if two angles form a linear pair?

Back

Two angles form a linear pair if they are adjacent and their non-common sides form a straight line.
