What are opposite rays?

Back

Opposite rays are two rays that share a common endpoint and extend in opposite directions. For example, if point O is the common endpoint, then rays OB and OA are opposite rays.

What is the definition of a midpoint?

Back

Front

What is an angle?

Back

An angle is formed by two rays that share a common endpoint, known as the vertex of the angle.

Front

How do you find the distance between two points?

Back

To find the distance between two points (x1, y1) and (x2, y2), use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which means their corresponding sides and angles are equal.

Front

What is the reflexive property?

What is the difference between a line and a line segment?

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.

Front

What is a complementary angle?

Back

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