Geometry Vocabulary Basics

Front

What is the distance formula in geometry?

Back

The distance between two points (x1, y1) and (x2, y2) is given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

Define a right angle.

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

What does it mean for point B to be the midpoint of segment AC?

Back

It means that point B divides segment AC into two equal parts, so AB = BC.

Front

What is the midpoint formula?

Back

The midpoint M of a segment with endpoints (x1, y1) and (x2, y2) is given by: M = ((x1 + x2)/2, (y1 + y2)/2).

Front

Solve for x: 2x - 7 = 8.

Back

x = 7.5.

Front

What is the definition of a segment bisector?

Back

A segment bisector is a point, line, or segment that divides another segment into two equal parts.

Front

What is the sum of the angles in a triangle?

Back

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

Front

Define complementary angles.

Back

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