Angle Pair Relationships & Triangles

Front

What are the different types of angle pairs?

Back

1. Complementary Angles: Two angles that add up to 90 degrees. 2. Supplementary Angles: Two angles that add up to 180 degrees. 3. Vertical Angles: Angles opposite each other when two lines intersect; they are equal. 4. Adjacent Angles: Two angles that share a common side and vertex.

What is the definition of corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

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

Back

The sum of the interior angles of a triangle is always 180 degrees. To find a missing angle, subtract the sum of the known angles from 180 degrees.

What is the relationship between angles B and W if they are congruent?

Back

If angles B and W are congruent, they have the same measure.

Front

What is the equation to find the value of x in angle relationships?

Back

The equation can vary based on the specific angle relationships, but it often involves setting up an equation based on the relationships (e.g., supplementary, complementary) and solving for x.

Front

What are vertical angles and how do they relate to each other?

Back

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

Front

What is the definition of supplementary angles?

Back

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

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

How can you determine if two angles are corresponding?

Back

Two angles are corresponding if they are in the same relative position at each intersection of two lines cut by a transversal.

Front

What is the sum of the angles in a triangle?

Back

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