Segments and Angles

Front

What is a segment in geometry?

Back

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

Front

Define 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 formula to find the midpoint between two points on a number line?

Back

Midpoint = (x1 + x2) / 2, where x1 and x2 are the coordinates of the two points.

Front

How do you calculate the distance between two points on a number line?

Back

Distance = |x2 - x1|, where x1 and x2 are the coordinates of the two points.

Front

What is the sum of the angles in a triangle?

Back

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

Front

What is a complementary angle?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What is a supplementary angle?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If m∠A + m∠B = 90°, what can you say about angles A and B?

Back

Angles A and B are complementary.

Front

If m∠C + m∠D = 180°, what can you say about angles C and D?

Back

Angles C and D are supplementary.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal; they are formed by two intersecting lines.
