Fall Semester Exam Review

Front

What is the relationship between points R, S, and T if R is between S and T?

Back

R is a point that lies on the line segment connecting points S and T.

Front

If SR = 2x + 2, RT = 4x + 3, and ST = 7x, how do you find ST?

Back

Set up the equation: SR + RT = ST. Substitute the expressions and solve for x.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a method to prove triangles are congruent.

Front

What is the definition of an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

Front

What is the measure of an angle if it is supplementary to 101°?

Back

The measure is 79° because supplementary angles add up to 180°.

Front

How do you find the slope of a line given two points?

Back

Use the formula: slope (m) = (y2 - y1) / (x2 - x1).

Front

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

Back

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

Front

What is the definition of perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What does it mean for two angles to be vertical angles?

Back

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