What is an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

What is the relationship between the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

What is a right angle?

Back

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

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

How do you find the value of x in a parallelogram?

Back

To find the value of x in a parallelogram, use the properties of parallel lines and angles to set up equations.

What is a straight angle?

Back

A straight angle is an angle that measures exactly 180 degrees.

Front

What is the formula for the slope of a line?

Back

The slope (m) of a line is calculated as m = (y2 - y1) / (x2 - x1).

Front

What are opposite reciprocals?

Back

Opposite reciprocals are two numbers whose product is -1; for example, 2 and -1/2.
