2024 Geometry Semester 1 Exam

Front

What is the slope of a line that is perpendicular to a line with slope 2?

Back

The slope of a line that is perpendicular to a line with slope 2 is -\frac{1}{2}.

Front

Define a linear pair of angles.

Back

A linear pair of angles are two adjacent angles formed when two lines intersect. The sum of the angles in a linear pair is always 180 degrees.

Front

What is the relationship between the slopes of two perpendicular lines?

Back

The product of the slopes of two perpendicular lines is -1.

Front

If two triangles are similar, what does that imply about their corresponding angles and sides?

Back

If two triangles are similar, their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is the formula for finding the distance between two points (x1, y1) and (x2, y2) in a coordinate plane?

Back

Front

What is the definition of a perpendicular bisector?

Back

A perpendicular bisector is a line that divides a segment into two equal parts at a 90-degree angle.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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.

Front

If m∠A = 40° and m∠B = 140°, what type of angles are A and B?

Back

Angles A and B are supplementary angles because their sum is 180 degrees.

Front

What is the definition of similar triangles?

Back

Similar triangles are triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are proportional.
