Semester 1 Final Exam

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal. They are congruent.

Front

How do you find the distance between two points (x1, y1) and (x2, y2)?

Back

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

If two angles are supplementary, what is their sum?

Back

The sum of two supplementary angles is 180 degrees.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What is the formula for finding the missing angle in a triangle?

Back

To find a missing angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

What is the relationship between the angles formed by two parallel lines cut by a transversal?

Back

The alternate interior angles are congruent, and the corresponding angles are also congruent.

Front

How do you determine if two lines are parallel using slopes?

Back

Two lines are parallel if they have the same slope.
