A polygon's diagonals are line segments from one ______ to another nonconsecutive ______.
The side lengths of a right triangle, 3, 4, and 5, form a Pythagorean ______.
Given the lengths of sides, we can use "trig" functions to find missing angles by using their ________: sin^(-1), cos^(-1), and tan^(-1).
_______ = (leg opposite to the angle) / (leg adjacent to the angle)
If the altitude is drawn to the hypotenuse of a right triangle, then the two triangles formed are _______ to the original triangle and to each other.
Two right triangles are said to be congruent if their _____________ hypotenuse and at least one of their legs are congruent.
_________ Pythagorean Theorem: If the square of one side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
____ = (leg opposite to the angle) / (hypotenuse)
In a right triangle, the square of the __________ (the side opposite to the right angle) is equal to the sum of the squares of the other two sides.
Angles of _________ are angles above the horizon.
If the ________ is drawn to the hypotenuse of a right triangle, then the two triangles formed are similar to the original triangle and to each other.

______ = (leg adjacent to the angle) / (hypotenuse)
The number of _________ of an n-sided polygon is [n(n-3)]/2.
Hypotenuse-___ (HL) Theorem is another way to prove triangles are congruent.
A(n) ___________ triple is a set of positive integers, a, b, and c that satisfy the ___________ Theorem, a² + b² = c².
In a right triangle, the altitude from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of the altitude is the _________ mean of the lengths of the two segments.
Understanding how to work with interior angles, exterior angles, and regular ________ will help us find the length of certain segments such as a side, radius, apothem, and diagonals, among others.
Angles of __________ are angles below the horizon.
In a right triangle, the altitude from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of each leg of the right triangle is the geometric ____ of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.
