Question
In the we have $\angle1=\angle2,\angle2=\angle3.$ Show that $\angle1=\angle=3$
✓
Answer
We have,
$\angle1=\angle2$ [Given]
$\angle2=\angle3$ [Given]
Now, by Euclid's axiom 1, things which are equal to the same thing are equal to one other.
Hence, $\angle1=\angle3$
$\angle1=\angle2$ [Given]
