Q1.
If Angle A is greater than Angle B, how can I express this mathematically?
A < B
A = B
Correct answer: A > B
B > A
Q2.
If Angle Y = Angle X = Angle Z, which of the following is true?
X + Y + Z = 180
X + Y + Z = 3A
Correct answer: X + Y + Z = 3X
X + Y = Z
Q3.
If g > h, then which of the following results in the greater value?
180 - g
Correct answer: 180 - h
The previous two responses result in the same amount
Q4.
You are given that: 360 - R = S. Which of the following statements is correct?
360 + S - R = 0
360 = S - R
Correct answer: 360 = S + R
S = 180
Q5.
