Vertical and Corresponding angles

Vertical and Corresponding angles

​Vertical Angles

​When two lines intersect, 4 angles are created.

• ​The angles that are across from each other are always congruent.

• ​These are called VERTICAL ANGLES.

Multiple Choice

What is the measure of angle b?

• $$65\degree$$  

• $$180\degree$$  

• $$115\degree$$  

• $$75\degree$$  

​

​Two angles that are next to each other on a straight line are SUPPLEMENTARY (aka they add up to 180 degrees).

Multiple Choice

What is the measure of angle c?

• $$65\degree$$  

• $$180\degree$$  

• $$115\degree$$  

• $$75\degree$$  

​

​When two lines are cut by a third line, that third line is called a TRANSVERSAL.

​Parallel lines

​When two lines have arrows on them, it indicates that they are parallel.

• ​When parallel lines are cut by a transversal, you have CORRESPONDING ANGLES are congruent.

• ​Angle e must be 65 degrees since is corresponds with the 65 degree angle.
