Answer:
1. line AB ≅ line CD (its congruent)
2. m<ZXY - m<WXZ = m<WXY
Step-by-step explanation:
1.
A (-3, 2)
B (0, 3)
C (-1, 2)
D (2, -3)
find:
determine if AB ≅ CD (congruent or non-congruent)
solution:
Length AB = √(0+3)² + (3+2)² = 5.8
Length CD = √(2+1)² + (-3-2)² = 5.8
therefore,
line AB ≅ line CD (its congruent)
2.
m<ZXY - m<WXZ = m<WXY
given:
point Z is in the interior of <WXY creating XZ.
if m<WXZ = 20
m<WXY = 100
find:
what would equation would you set up to find the missing angle measure?
solution:
Since Z is interior of <WXY
m<ZXY - m<WXZ = m<WXY
<WXY = 100 - 20 = 80°
therefore, the equation would be m<ZXY - m<WXZ = m<WXY
