Geometry Review #2

Front

What is the definition of a midpoint in geometry?

Back

A midpoint is a point that divides a line segment into two equal parts.

Front

If A is the midpoint of segment BC, and AB = 4x + 10, what equation can be used to find x?

Back

4x + 10 = 5x - 10.

Front

How do you find the midpoint of two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the distance formula used to find the distance between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they never intersect and are always the same distance apart.

Front

What is the Corresponding Angles Converse theorem?

Back

If two lines are cut by a transversal and the corresponding angles are equal, then the lines are parallel.

Front

What is the Alt. Interior Angles Converse theorem?

Back

If two lines are cut by a transversal and the alternate interior angles are equal, then the lines are parallel.

Front

What is the formula to calculate the distance between the points (3, 24) and (7, 56)?

Back

Distance = √((7 - 3)² + (56 - 24)²) = 32.2.

Front

If two lines are parallel, what can be said about the angles formed by a transversal?

Back

The corresponding angles are equal, alternate interior angles are equal, and same-side interior angles are supplementary.

Front

What is the Vertical Angles Theorem?

Back

Vertical angles are equal when two lines intersect.
