Question

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

Answer 1

Answer:

$m = n$ --> Corresponding angle

$x = y$ --> Vertically opposite

Step-by-step 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

$x + n = y + m$
