12/6 - Final Review Part 1

Front

What is the measure of angle TSR if m∠TSR = 120°?

Back

m∠TSR = 120°.

Front

If m∠HSR = x + 63 and m∠TSH = x + 73, how do you find x?

Back

Set up the equation based on the angle relationships and solve for x.

Front

What is the relationship between the slopes of two lines if they are perpendicular?

Back

The product of their slopes is -1.

Front

What is the equation of a line in slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the segment addition postulate state?

Back

If points A, B, C are collinear with B between A and C, then AB + BC = AC.

Front

What is the result of reflecting a shape over the y-axis followed by reflecting it over the x-axis?

Back

The shape will be rotated 180° around the origin.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the transformation that moves a shape without changing its size or orientation?

Back

Translation.

Front

What is the measure of an angle if it is complementary to a 45° angle?

Back

The measure is 45°.
