Slope Triangles

Front

What is the definition of slope?

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the rise (vertical change) to the run (horizontal change).

How do you calculate the slope of a line?

Back

Front

What does it mean if two lines have the same slope?

Back

If two lines have the same slope, they are parallel and will never intersect.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If triangle ABC and triangle DEF are similar, what can be said about their slopes?

Back

The slopes of triangle ABC and triangle DEF are equal.

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What is the relationship between similar triangles and their slopes?

Back

Similar triangles have proportional sides and equal slopes.

Front

How can you determine if two triangles are similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the rise in the slope formula?

Back

The rise is the vertical change between two points on a line.
