ACT ON
A. For each of the following, write on the space provided the condition that supports
why quadrilateral WXYZ is a parallelogram.
1. OX OZOW OY
X х
2. XY WZWXYZ
3. XY WZ, XY || WZ
3
Z
4. LXZZ,2W LY
5. WX || ZY,WX = ZY
6. ZX+ZY :
180, 2X + 2W = 180
B. Give the measures of the other three angles of parallelogram WXYZ.
1. If mW = 60, M2X = m_Y = mZZ =
2. If mzx = 110, m_W = m_Y = mzz =
3. If m_Y = 75, m2X = m_W =
4. If mzz = 98, m_X = m_Y = mZW=
- mzi =
