Geometry Final Review #1

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

What is the distance formula in a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²) where (x1, y1) and (x2, y2) are the coordinates of the points.

Front

What is the slope of parallel lines?

Back

The slope of parallel lines is the same; they never intersect.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What is the definition of a linear pair?

Back

A pair of adjacent angles that are supplementary, meaning they add up to 180 degrees.

Front

How do you find the slope of a line given two points?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.
