Question

M=n give reason
2)x=y. give reason
3) y+n = x+m give reason​

Answer 1

`m = n` --> Corresponding angle

`x = y` --> Vertically opposite

Explanation:

Given

The attachment

Required

State the reason for the given statements

m = n

m and n are corresponding angles.

So:

`m = n`

x = y

x and y are vertically opposite angles

So:

`x = y`

`y + n = x + m`

In (b)

`x = y`

Add m to both sides

`x + m = y +m`

In (a)
`m = n`

So, substitute n for m on the left hand side

`x + n = y + m`
