How well do you know angle relationships??

• Two angles whose sum is 90 ̊

• Two angles whose sum is 180 ̊

• The angles opposite of each other when intersected by a line.

• The angles next to each other who share a common vertex and a common side

• The angles who when crossed by a transversal are in the matching corners

• An angle that is less than 90 ̊

• An angle that is greater than 90 ̊

• Two angles that have the same measurement

Which angles are corresponding angles?

A.Angles M and NB.Angles R and TC.Angles M and QD.Angles N and O

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

Supplementary Angles!!!

(Two angles whose sum is 180°)(Picture hyperlinks back to question)

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

Supplementary Angles!!!

(Two angles whose sum is 180°)

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!

WHOOPS! Try Again! What is the vocabulary that matches with this definition?

Adjacent Angles!

Picture hyperlinks back to the question

Oh No!! This is the definition of another one of our vocabulary words. Can you determine which one??

OBTUSE ANGLES!!

Great Job!! You are CORRECT!!

Congruent angles have the same

measurement!

Picture hyperlinks to next question

What type of angles are these?

A. Complementary and Adjacent

B. Supplementary and VerticalC.ComplementaryD. Adjacent and Corresponding

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.

Try again! • What is the definition of a

supplementary angle??Two angles who sum adds up to 180˚

•What is the definition of vertical angles??

The angles opposite of each other when intersected by a line

Hyperlinks back to question

ALMOST CORRECT! Try again!• These angles are complementary but

they also fall under another vocabulary term that we have.

Hyperlinks back to question

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??

Hyperlinks back to question

What is the difference between an obtuse and acute angle?

A. Obtuse angles adds up to 180 ̊, while acute angles adds up to 90 ̊

B. Obtuse angles are less than 90°, while acute angles are greater than 90 °

C. Obtuse angles have the same definition as acute angles

D. Obtuse angles are greater than 90 °, while acute angles are less than 90 °

Try again!!• You are thinking of two different

vocabulary words. Can you tell me which ones you are thinking of??

Supplementary and complementary angles!

Picture hyperlinks back to question

VERY CLOSE! Try again!!• Reread this definition and tell me what you

believe needs to be fixed in order to make this a true definition of each word!

Picture hyperlinks back to question

Oh No! Try again!!• Silly children! We do not have any two

vocabulary words that have the same definition!

Picture hyperlinks back to question

CORRECT!! Great Job!!

Which ones are which again?? Obtuse or acute??

ACUTE!

OBTUSE!

Picture hyperlinks to next question

What relationships do angle D and angle H have in common?

A.They are supplementary and complementary.

B.They are corresponding and congruent angles

C.They are vertical and adjacent angles

D.They have no relationship

Uh Oh, Try Again!!• What is the definition of supplementary

angles??• Two angles who sum is 180 °

• What is the definition of complementary angles??

• Two angles who sum is 90 °

ANGLES ANGLES ANGLES!Hyperlinks back to question

YOU ARE CORRECT!• What is the definition of corresponding

angles??• The angles who when crossed by a

transversal are in the matching corners

• What is the definition of congruent angles??

• Two angles that have the same measurement

TRY AGAIN!!• What is the definition of vertical angles??

• The angles opposite of each other when intersected by a line.

• What is the definition of adjacent angles?? • The angles next to each other who

share a common vertex and a common side

Hyperlinks back to question

Uh Oh! No relationship between these angles??

• Every two angles in this picture have some sort of relationship!

• We can not leave these two angles out!
