1st Semester Exam Review 24-25

Front

What are parallel lines?

Back

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

Front

What are perpendicular lines?

Back

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

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is a translation in geometry?

Back

A translation is a transformation that slides a figure from one position to another without turning it.

Front

How do you find the measure of an angle in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees. You can find the measure of an unknown angle by subtracting the sum of the known angles from 180.

Front

What is the measure of angle A if angle B is 40 degrees and angle C is 40 degrees?

Back

Angle A = 180 - (40 + 40) = 100 degrees.

Front

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

Back

When a transversal crosses parallel lines, several pairs of angles are formed, including corresponding angles, alternate interior angles, and alternate exterior angles, which have specific relationships.

Front

What is the formula for finding the distance between two parallel lines?

Back

The distance between two parallel lines can be found using the formula: Distance = |c2 - c1| / sqrt(a^2 + b^2), where the lines are in the form ax + by + c = 0.
