Hi!
The line of symmetry is a line that has equal parts of the shape on both sides of it.
Look at the shape. Is there a place where you can put a line that divides it in half? Or will one part of it still be unequal?
I included an image that shows the line of symmetry. Note how the halves of the triangle on both sides of the line are equal.
The line of symmetry is x = 3
Hope this helps! :)

from the given figure two lines are parallel to each other. If ∠11=62 then ∠12 =(180- 62)=118,∠8=62 (vertically opposite angles are parallel) and ∠4=62 corresponding angles are equal )If ∠8=62 then ∠3=62 (corresponding angles in a parallel lines are equal) If ∠14=38 then∠13=(180-38)=142 , ∠6=38 (corresponding angles) and ∠9=38 (vertically opposite angles).
If ∠6=38 then∠1=38 (vertically opposite angles)
If ∠1=38 and ∠3=62 then ∠2=180-(38+62)=80 and if ∠2=80 then ∠5=80 (vertically opposite angles)
Hey there!
⇒ Use the vertex as the middle letter, and the point from each side (<ABC or <CBA)
⇒ Use the vertex only (<B)
⇒ Use a number (<1)
⇒ Acute angle: less than 90°
⇒ Right angle: exactly 90°
⇒ Obtuse angle: between 90° and 180°
⇒ Straight angle: exactly 180°
Thank you,
