How does any triangle side length compare to the other two lengths of the triangle?
|
The length of any side of a triangle must fall between the sum and difference of the lengths of the other two sides. If we have two sides of length 5 and 7, then the third side must have length between (7 + 5) and (7 - 5):

What makes a triangle congruent?
|
A triangle is congruent if it has the same dimensions as another triangle. To prove congruence you need SSS (side,side,side) ASA (Angle, Side, Angle) SAS (Side, Angle, Side) AAS (Angle, Angle, Side) https://my.knewton.com/review/concept/315

What does the Central Theorem state?
|
The central angle theorem states that for any two points on a circle, the measure of any associated inscribed angle with a vertex on the major arc will always be half of the measure of the associated central angle.
