Angle Relationships and PLCBT

Angle Relationships! yay!

First let's review some of the angle relationships you (should have) learned in 7th grade

Multiple Choice

What is the measure of ∠BAD?

• 123^o

• 23^o

• 90^o

• 180^o

Multiple Choice

Calculate the missing measurement

• 85 degrees

• 90 degrees

• 25 degrees

• 45 degrees

Multiple Choice

What is the value of A?

• 148 degrees

• 24 degrees

• 124 degrees

Multiple Choice

What is the measurement of x?

• 180

• 50

• 55

Multiple Choice

∠1 and ∠3 can best be described as -

• complementary angles

• supplementary angles

• vertical angles

• adjacent angles

Multiple Choice

Find the missing angle.  Find x.

• 15^o

• 50^o

• 130^o

• 165^o

Multiple Choice

If m∠1 = 30°, then m∠3 = 

• 30°

• 60°

• 150°

• undetermined

Multiple Choice

Vertical angles are always

• acute

• total 180 degrees

• congruent (equal measures)

• adjacent angles

Multiple Choice

Which angles are vertical angles?

• $$\angle8\ \ and\ \angle7$$

• $$\angle8\ and\ \angle6$$

• $$\angle8\ and\ \angle5$$

Multiple Choice

What is the value of x?

• 37

• 72

• 108

• 18

Open Ended

Explain in your own words what parallel lines are

• Two or more LINES that lie in the same plane and NEVER INTERSECT each other (never cross)

• To be parallel the lines must maintain the same CONSTANT rate of change

Parallel lines

​Lines a and b both have a slope of 0

Lines p and q have the same (negative) slope

A LINE, ray, or line segment that INTERSECTS other lines, rays, or line segments on a plane at different intersecting points.

​

Transversal

In this unit we are learning about the angles that are formed when you have

​

TWO PARALLEL LINES CUT BY A TRANSVERSAL

and the relationships that these angles have with one another

​

Multiple Choice
