HW W30: Angle Relationships, Sqr and Cube Roots, Linear Equation

Match the following

• Complementary Angles

• 
• Linear Pair

• 
• Adjacent Angles

• 
• Vertical Angles

• 
• Supplementary Angles

• 

Vertical angles are 2 angles that are directly ​ (a)   from each other when 2 lines cross, and they are ​ (b)   ​ .

Supplementary angles add up to be ​ (c)   degrees, and they don't have to be next to each other.

Complementary angles add up to be ​ (d)   degrees, and they don't have to next to each other.

• opposite
• always congruent
• 180
• 90

Adjacent angles are two angles that share a common ​ (a)   and a common side. They are next to each other.

A linear pair are two ​ (b)   angles that form a straight line. They are always ​ (c)   , adding to 180 degrees.

A trasversal is a ​ (d)   that crosses two or more other lines.

• vertex
• adjacent
• supplementary
• line

Corresponding angles are angles are in​ (a)   , and they are only ​ (b)   if the two lines are ​ (c)   .

Angles 3 and 7 are corresponding angles, and so are angles 2 and ​ (d)   , and angles 1 and ​ (e)   .

• matching corners
• congruent
• parallel
• 6
• 5
• 4
• 8

Alternative Interior angles are ​ (a)   the lines, l and m, and on the ​ (b)   of the transversal, and they are only ​ (c)   if the lines are ​ parallel .

Angles 3 and ​ (d)   are a pair of Alternate Interior Angle, and another pair is angles ​ 4 and ​ (e)   .

• inside
• opposite side
• congruent
• 6
• 5
• 1
• 7
• outside
• same side
• supplementary

Same-Side Interior angles are ​ (a)   the lines, l and m, and on the ​ (b)   of the transversal, and they are only ​ (c)   if the lines are ​ parallel .

Angles 3 and ​ (d)   are a pair of Alternate Interior Angle, and another pair is angles ​4 and ​ ​ (e)   .

• inside
• same side
• supplementary
• 5
• 6
• 1
• 7
• outside

A pair of corresponding angles is congruent ...

• only when the two lines are parallel.

• always!

• only when the lines are not parallel.

• only when there is a transversal
