Vertical Angles

Name the PAIRS of angles that are Vertical Angles.

Vertical angles are congruent

Vertical Angles

∠B =

Vertical Angles

Given: m∠a = 77^o

What is m∠b

Vertical Angles

Given: ∠1 = 50^o

What is m∠2

m∠1 + m∠2 =180^o

50^o + m∠2 =180^o

m∠2 =180^o - 50^o = 130^o

Vertical Angles

Given:

∠1 = 50^o and ∠2 = 130^o

What is m∠3

What is m∠4

What does m∠1 + m∠4 =

Vertical Angles

Given:

∠1 = 30^o

What is m∠3

What does m∠1 + m∠2 =

What is m∠2

Vertical Angles

Given:

∠1 = 37^o

What is m∠2

What does m∠1 + m∠4 =

What is m∠2
