8th Final - Transversal Angles And Triangle Theorems

Front

What is a transversal?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

Front

What is the Alternate Interior Angles Theorem?

Back

The Alternate Interior Angles Theorem states that if a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180°.

Front

What are vertical angles?

Back

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

Front

What is the definition of an acute angle?

Back

An acute angle is an angle that measures less than 90°.

Front

What is the definition of an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90° but less than 180°.

Front

What is the definition of a right angle?

Back

A right angle is an angle that measures exactly 90°.

Front

How do you find the measure of an angle when given its supplement?

Back

The measure of an angle's supplement can be found by subtracting the angle from 180°.

Front

How do you find the measure of an angle when given its complement?

Back

The measure of an angle's complement can be found by subtracting the angle from 90°.
