Exit Review, Angles and Segments

Front

What is the definition of a segment in geometry?

Back

A segment is a part of a line that is bounded by two distinct endpoints.

Front

What is the formula for finding the length of a segment between two points (x1, y1) and (x2, y2)?

Back

The length of the segment is given by the formula: \(d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\).

Front

What is an angle in geometry?

Back

An angle is formed by two rays (sides of the angle) that share a common endpoint (the vertex).

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

What is the difference between acute, obtuse, and right angles?

Back

An acute angle is less than 90 degrees, a right angle is exactly 90 degrees, and an obtuse angle is greater than 90 degrees but less than 180 degrees.

Front

How do you denote an angle using its vertex and points on its sides?

Back

An angle can be denoted using the vertex and points on its sides, for example, \(\angle BAC\) where A is the vertex.

Front

What is the relationship between complementary angles?

Back

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

Front

What is the relationship between supplementary angles?

Back

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

Front

What is the definition of a vertical angle?

Back

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

Front

What is the definition of adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.
