What is the definition of cosine in a right triangle?

Back

Cosine of an angle A (cos A) is defined as the ratio of the length of the adjacent side to the length of the hypotenuse.

How do you determine the translation of a point in a coordinate plane?

Back

To determine the translation of a point, subtract the original coordinates from the new coordinates. The result gives the horizontal and vertical shifts.

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

Front

What are vertical angles?

Back

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

Front

What is the definition of supplementary angles?

Back

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

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside two parallel lines. They are equal.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position at each intersection where a straight line crosses two others. They are equal if the lines are parallel.
