Geometry A Unit 2: Transversal

Front

What is a transversal in geometry?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal and are equal to each other.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines on opposite sides of a transversal and are equal.

Front

What are vertical angles?

Back

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

Front

How do you solve for x in the equation 7x - (5x + 30) = 180?

Back

First, simplify the equation: 7x - 5x - 30 = 180, then combine like terms: 2x - 30 = 180, and finally solve for x: 2x = 210, x = 105.

Front

What is the relationship between supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the equation for corresponding angles when two parallel lines are cut by a transversal?

Back

If two parallel lines are cut by a transversal, then the corresponding angles are equal.

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

How do you identify alternate exterior angles?

Back

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

Front

What is the formula to find the measure of an angle when given its supplementary angle?

Back

If angle A is supplementary to angle B, then A + B = 180 degrees.
