Prove that the above triangle is a triangle

An isosceles triangle has 2 equal sides and 2 equal angles;

But in this case, we're dealing with only angles.

Once, we can prove that triangle EDF has 2 angles, then it has been proven that it is an isosceles triangle.

The first step is to calculate

First, it should be noted that angle on a straight line equals 180;

This implies that

Subtract from both sides

The next step is to calculate the measure of

It should be noted that angles in a triangle add up to 180;

This implies that

Where

becomes

Subtract 90 from both sides

Perform arithmetic operation on y and -y/2

Subtract y/2 from both sides

At this point, it has been proven that triangle EDF is isosceles because

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
