Solving problems involving angles and equations

Name the vertical angle to

∠h.

• ∠i

• ∠f

• ∠g

• ∠j

Find the measure of x.

The value of angle b is ______ degrees. (only input the number)

How do you feel about vertical & adjacent angles now

• 🤔 I need help

• 😐 I kind of get it, but need more practice

• 😎 I think I got it!

What angle pair is pictured...adjacent or vertical?

• Alternate Interior Angles

• Supplementary Angles

• Vertical Angles

• Corresponding Angles

What would be an appropriate statement to write in the box based on the given diagram, using the reason “Vertical Angles Theorem”?

• <4 and <2 are vertical angles

• <3 is congruent to <1

• m<2 = m<4

• <1 and <4 are supplementary

Name a pair of vertical angles in the figure.

• ∠2 and ∠4

• ∠6 and ∠5

• ∠1 and ∠4

• ∠1 and ∠6

Which of the following statements is true about vertical angles?

• They are always acute

• They are always supplementary

• They are always congruent

• They are always adjacent

What is the angle measurement for vertical angles?

• 180 degrees

• 90 degrees

• The opposite angles are equal. So, angle b would equal 47 degrees.

∡a and ∡b are vertical angles.

If m∡a = 3x and m∡b = 30, find the value of x.

• x= 10

• x = -5

• x = -1

• x = 4
