Day 1 - #1-12 Fall Geometry Final Exam Review

Front

What is the formula to find the coordinates of a point that is a certain fraction of the distance between two points A(x1, y1) and C(x2, y2)?

Back

The coordinates of point B that is k fraction of the distance from A to C can be found using the formula: B = (1-k)A + kC, where k is the fraction.

Front

How do you determine the quadrant of a point given its coordinates (x, y)?

Back

A point (x, y) is in Quadrant I if x > 0 and y > 0, Quadrant II if x < 0 and y > 0, Quadrant III if x < 0 and y < 0, and Quadrant IV if x > 0 and y < 0.

Front

What is the slope of a line perpendicular to a line with slope m?

Back

The slope of a line perpendicular to a line with slope m is -1/m.

Front

What is the distance formula between two points B(w, x) and O(y, z)?

Back

Front

How do you find the midpoint PM of a line segment with endpoints P(x1, y1) and M(x2, y2)?

Back

The midpoint PM is calculated using the formula: PM = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the condition for two lines to be parallel?

Back

Two lines are parallel if they have the same slope.
