Answer:
Step-by-step explanation:
m ∠XOY = m ∠WOV
so, m XY = m WV --- (i)
{ If angle subtended by two arcs at the center are equal, then length of arc are equal}
m YZ = m ZW ------- (ii) {given}
Add (i) and (ii)
XY + YZ = WV + ZW
XZ = ZV
Hence proved.
Answer:
Given that m ∠XOY = m ∠WOV then m XY = m WV, because central angles are equal to arcs.
Given: m YZ = m ZW
The addition of arcs XY and YZ make arc XZ, that is: m XY + m YZ = m XZ
The addition of arcs ZW and WV make arc XZ, that is: m WV + m ZW = m ZV
Then, m XZ = m ZV
