What is the perpendicular bisector?

Back

The perpendicular bisector is a line that divides a line segment into two equal parts at a 90-degree angle.

Front

What are vertical angles?

Back

Vertical angles are angles that are opposite each other when two lines intersect.

Front

What is the formula for the area of a triangle given vertices A(x1, y1), B(x2, y2), C(x3, y3)?

Back

Area = 1/2 * |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

How do you calculate the weighted average?

Back

Weighted average = (sum of (value * weight)) / (sum of weights).

Front

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

Back

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

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

What is the definition of adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex.
