What does the side splitter theorem state?
The side splitter theorem states that if a line is parallel to a side of a triangle and the line intersects the other two sides, then this line divides those two sides proportionally. The side splitter theorem is a natural extension of similarity ratio, and it happens any time that a pair of parallel lines intersect a triangle.
How to solve 45-45-90 triangles?
When given the length of the hypotenuse of a 45°-45°-90° triangle, you can calculate the side lengths by simply dividing the hypotenuse by √2. Note: Only the 45°-45°-90° triangles can be solved using the 1:1: √2 ratio method .

What is the formula for 30 60 90 triangle?
The sides of a 30-60-90 triangle are always in the ratio of 1:√3: 2. This is also known as the 30-60-90 triangle formula for sides y: y√3: 2y. Let us learn the derivation of this ratio in the 30-60-90 triangle proof section. This formula can be verified using the Pythagoras theorem.
What is the meaning of midline theorem?

How do you find the missing side of a triangle?
Given two sidesif leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)if leg b is unknown, then. b = √(c² - a²)for hypotenuse c missing, the formula is. c = √(a² + b²)

How does the triangle angle bisector theorem work?
The angle bisector of a triangle divides the opposite side into two parts proportional to the other two sides of the triangle. In a triangle, if the interior point is equidistant from the two sides of a triangle, then that point lies on the angle bisector of the angle formed by the two line segments.
