Front

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

Back

The midpoint M is given by M = ((x1 + x2)/2, (y1 + y2)/2).

Front

If the midpoint of segment EF is (-2,8) and endpoint E is (4,0), how do you find the coordinates of endpoint F?

Back

Use the midpoint formula: F = (2 * midpoint - E). In this case, F = (2 * (-2, 8) - (4, 0)) = (-8, 16).

Front

What does it mean for two lines to be parallel in terms of their slopes?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is a transversal in geometry?

Back

A transversal is a line that intersects two or more other lines at distinct points.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

If angle JHG measures 161 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle is 180 - 161 = 19 degrees.

Front

What is the relationship between alternate interior angles when two lines are parallel?

Back

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

Front

How do you determine if two lines are parallel using angle measures?

Back

If corresponding angles are equal or alternate interior angles are equal, the lines are parallel.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal.

Front

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

Back

The sum of the interior angles of a triangle is always 180 degrees.
