The longest chord possible in a circle is one that is from one point on the circumference to its opposite point i.e. a chord that bisects the circle. Or to put it simply one straight down the middle
Wait, what? I believe diameter is the measurement straight across the middle of a circle, not a unit of measurement. So if a circle were to be 27 inches in diameter, it would be 27 inches from one side of the circle to the other, with the line going exactly through the center of the circle. Basically, cutting the circle in half.
To use a protractor for circles you find the middle of the circle and you then put the dot on the hole then you measure
Sum of all the angles in the triangle has to be 180 degrees. Let's mark the largest angle as x. Then, smallest angle will be 0.5x and the middle one x-25. x + 0.5x +x - 25 = 180, which is after simplyfying: 2.5x = 205 x = 82 degrees -> the largest angle, x-25 = 57 degrees -> middle one, 0.5x = 41 degrees -> the smallest angle.
The middle. Such as the center of a circle or triangle.

The sign of the deathly hallows is a triangle with a circle inside and thin line down the middle. Each shape represents one of the hallows. The triangle represents the cloak of invisibility, the circle is the resurrection stone and the line is the elder wand.

No way! An easy example is the centroid and circumcenter of a right-angle triangle. Circumcenter will be exactly on the middle of the hypotenuse which obviously cannot be the centroid. Centroid is the point where all three lines are connecting all the three vertices and the middle of the line opposite the respective vertex. Circumcenter is the center of the circle passing through all the vertices. As it is known, a right-angle triangle will always fall within a semicircle, meaning the circle center will always be on the middle of the hypotenuse.
Especially if it also has a vertical line in the middle, it may be a reference to the Deathly Hallows of Harry Potter.
The sign of the Deathly Hallows, first introduced by Xenophilius Lovegood at the Weasley wedding, is how those searching for the Deathly Hallows reveal themselves to other "true believers" on the quest. It is depicted as a circle within a triangle, divided by a single vertical line. The line represents the Elder Wand, the circle is the Resurrection Stone, and the triangle is the Invisibility Cloak.
