In geometry, the definition of a triangle is a two-dimensional closed figure with three sides. Aside from this, it is proven that the sum of the angles of a triangle is 180°. This is a triangle's innate property. Therefore, any closed shape with three sides is a triangle and it follows that the sum of the three angles is equal to 180°.
It is logical therefore, that the first step in proving this is by using the definition of a triangle.
Reflection involves mirroring a point over a line.
<em>When L is reflected across the x and y axes, the new coordinates are (7,3)</em>
Given that:

When a point is reflected across the x-axis, the rule is:

So, we have:

When a point is reflected across the y-axis, the rule is:

So, we have:

Hence, the new coordinates of L are (7,3)

Answer is 1080 degrees
Formula for calculating angles in a polygon (Shape with 4 or more sides) is (n-2) x 180, where n is the number of sides on the shape. Octagon has eight sides, so you subtract it by 2, which is 6. Multiply that by 180 to get 1080, which is the sum of the angles.
