Pythagorean Theorem: Allows us to find the length of a missing side if we have the length of two sides of the triangle. Triangle Geometry: It allows us to find the measure of an angle of the triangle if we have the measure of two of ...
Thus, these two segments are the same length. That is, HI―≅JI―. Let's practice using these steps and definitions to find the perimeter of polygons with an inscribed circle. The first two examples will review finding the perimeter of irregular triangles, and the third example w...
Question: Using the figure below. Find the unknown angle measures. Vertical Angles: Vertical angles have a special significance in the field of geometry. Vertical angles are always congruent or in other words, equal in measure. The usage of this concept helps solve several problems associated with...
The area of a rectangle is the space occupied within the boundary of the rectangle. It is calculated by finding the product of the length and breadth (width) of the rectangle and is expressed in square units.

(c² = a² + b² – 2ab cosC) if you are given 3 sides and 0 angles, or if you are given two sides and the angle opposite the missing side. The Law of Sines (a/sinA = b/sinB = c/sinC) can be used any time you know the length of one side and its opposite angle ...
In geometry, two parallel lines are the lines that never intersect each other and have a constant distance between them. Two parallel lines make the same angle with the standard x-axis so the slope of the two parallel lines is always equal. When two parallel lines are cut by another li...
Find the cosecant of the product for both triangles, this number will be the length of the dividing line that forms the hypotenuse. The cosecant is often found on calculators as either "csc", "asin", or "sin^-1". For example the cosecant of 0.15 would be 8.63 (csc15 = 8.63). ...
The mean and median, and therefore the middle or midpoint of the line, has an x value of 5. The midpoint is (5, 4). How to find midpoint of vertical line segments To calculate the length of a vertical line segment, concentrate on the y values: ...
The area of a trapezoid can be calculated if the length of its parallel sides and the distance (height) between them is given. The area of a trapezoid with bases are 'a' and 'b' and height is 'h' is A = ½ (a + b) h. Learn this formula with proof and e
