Geometry Semester 1 Review

Front

What is the definition of a corresponding angle?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

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

Back

The midpoint M is given by the formula M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the definition of a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle in a specific direction.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal; they are the angles opposite each other when two lines intersect.

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

Back

Front

What is the definition of a linear pair of angles?

Back

A linear pair of angles are two adjacent angles formed when two lines intersect, and they are supplementary.

Front

What is the definition of a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments that do not cross each other.

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.
