Per 1 Part 1 Final for Second semester

Front

What is the definition of vertical angles?

Back

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

Front

If two angles are vertical angles, what can be said about their measures?

Back

The measures of vertical angles are equal.

Front

What is the sine function in trigonometry?

Back

The sine function relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the hypotenuse.

Front

How do you find the missing side of a right triangle using the sine function?

Back

Use the formula: opposite side = hypotenuse * sin(angle).

Front

What is the relationship between angles 5 and 3 if angle 5 measures 63 degrees and they are supplementary?

Back

Angle 3 measures 117 degrees because supplementary angles 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 the two lines.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a straight line crosses two others.

Front

What is the cosine function in trigonometry?

Back

The cosine function relates the angle of a right triangle to the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the tangent function in trigonometry?

Back

The tangent function relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the adjacent side.

Front

If angle 6 and angle 7 are vertical angles, what can be concluded about their measures?

Back

Angle 6 and angle 7 are equal in measure.
