Try geometry before trigonometry. While you can use trig to find every side and angle, geometry is usually quicker and easier. First, remember the sum of the angles of any triangle is always 180 degrees. If you know 2 angles of a triangle, you can always subtract their sum from 180 to ...
Using the Pythagorean theorem and trigonometry, find the hypotenuse and angle a in the figure. Using the Pythagorean theorem and trigonometry, find the hypotenuse and angles a and b in the figure. How to figure out the length of a hypotenuse with only one side? Show how to find hypote...
Two triangles are congruent if they have: exactly the same three sides and. exactly the same three angles. But we don't have to know all three...
Quadrilaterals are four sided polygons, with four vertexes, whose total interior angles add up to 360 degrees. The most common quadrilaterals are the rectangle, square, trapezoid, rhombus, and parallelogram. Finding the interior angles of a quadrilateral is a relatively simple process, and can b...

Focal lengthin zoom lenses also strongly affects sharpness, but there is no general trend relating sharpness to focal length. Included in theEXIF data. Three focal lengths are usually sufficient for ordinary zooms (with a zoom, i.e., focal length ratio under 5:1). Five are recommended for ...

How to use the properties of an equilateral triangle to find the length of its edges? Triangles: Triangles are two dimensional closed figures which have 3 edges and 3 angles. The angles add to 180 degrees and the sum of the two smaller sides is always greater than t...
The salvage runs the entire length of the material. Fabric grain The grain line of the fabric is broken up into three options: Lengthwise grain (warp) refers to the threads that run parallel to the selvage. Crosswise grain (weft) refers to the threads that run perpendicular to the selvage...
Step 2: To find the perimeter of ΔHGF, we will first find the length of each side: HG=HC+CG=5+3=8GF=GE+EF=3+14=17FH=FD+DH=14+5=19 Thus, the perimeter of ΔHGF is: HG+GF+FH=8+17+19=44 Example Problem 3 - Finding the Perimeter of Regular Polygons with an ...
