Angle Relationships and Unknown Measures

• Alternate Interior Angles

• Alternate Exterior Angles

• Same-side Interior Angles

• Corresponding Angles

• None of these

Vertical angles are always

• acute

• total 180 degrees

• congruent (equal measures)

• adjacent angles

Supplementary angles always add up to

Which angle is a vertical angle to with \angle7 ?

Which equation would you use to find x?

• 3x + 4 + 8x + 16 = 130

• 3x + 4 + 130 = 8x + 16

• 8x + 16 + 130 = 3x + 4

• 5

• 35

• 25

• 0

Which equation would you use to find x?

• 5x + 3 + 3 + 15x = 70

• 70 + 3 + 15x = 5 + 3

• 70 + 5x + 3 = 3 + 15x

If m∠RST = (12x -1)°, m∠RSU = (9x -15)°,
and m∠UST = 53°, find each measure.

• x = 13

  m∠RST = 155°

  m∠RSU = 102°

• x = 3

  m∠RST = 35°

  m∠RSU = 12°

• x = 22

  m∠RST = 263°

  m∠RSU = 183°

• x = 8

  m∠RST = 95°

  m∠RSU = 57°

Which equation would you use to find x?

• 12x - 8 + 136 = 4x

• 12x - 8 + 4x = 136

• 4x + 136 = 12x - 8

Find the value of x.

• 18°

• 28°

• 38°

• 118°
