Geometry Fall 24 Final Exam Review

Front

What is the midpoint formula for a line segment with endpoints A(x1, y1) and B(x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

Find the midpoint of a line segment with endpoints A(3, 4) and B(7, 8).

Back

(5, 6)

Front

If the midpoint of PS is (2, 1) and P is (-1, 2), how do you find the endpoint S?

Back

Use the midpoint formula: S = (2*midpoint - P)

Front

What is the distance formula between two points A(x1, y1) and B(x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

Where does the distance formula come from?

Back

Pythagorean Theorem

Front

What is the definition of parallel lines?

Back

Lines that never intersect and have the same slope.

Front

Which value of x will show that lines l and m are parallel if their slopes are equal?

Back

x must be equal to the value that makes the slopes equal.

Front

What is the sum of the interior angles of a triangle?

Back

180°

Front

In a parallelogram, what is true about opposite angles?

Back

They are equal.

Front

If m∠R + m∠S = 180° in a parallelogram, what can you conclude about angles R and S?

Back

They are supplementary.
