This is a proof that the angles in a triangle equal 180°:
The top
line (that touches the top of the triangle) is
running parallel
to the base of the triangle.
So:
<span>
<span>angles A are the
same </span>
<span>angles B are the same </span>
</span>
And you can easily
see that A + C + B does a complete
rotation from one side of the straight line to the other, or <span>180°</span>

Step-by-step explanation:
Using the trigonometric identities
• tan x = 
• sec x =
, csc x = 
Consider the left side with x = Θ

=
=
× 
= 
=
× 
= secxcscx = right side ⇒ verified
