Oh No! You are thinking of a different definition. Can you determine what vocabulary word you are thinking of?
Supplementary Angles!!!

YAY!!! You are correct!Can you tell me the definition of a corresponding
angle??
Definition: The angles who when crossed by a transversal are in the
matching corners!
What is another example of a pair of
corresponding angles other than M and Q?Picture

Try Again!! You are thinking of a different vocabulary word. Can you determine which word you are
thinking of?
Vertical Angles!(The angles opposite of
each other when intersected by a line)

What is the definition of a pair of congruent angles?
A. Two angles who sum is 90°B. The angles next to each other
who share a common vertex and a common side
C. An angle that is greater than 90 #
D. Two angles that have the same measurement

Uh Oh! This definition is a different vocabulary word. Can you determine which one??
Complementary Angles!

You are CORRECT!
• What are complementary angles??Angles who sum adds up to 90˚
• What are adjacent angles??The angles next to each other who share a common vertex and a common side.

ALMOST CORRECT! Try again!• These angles are complementary but
they also fall under another vocabulary term that we have.

Oh No! Try again!
• Yes, these are a pair of adjacent angles!
• However, what is the definition of corresponding angles??
The angles who when crossed by a transversal are in the matching corners.
Are these angles corresponding?? Why or why not??
