How to Decompose Polygons to Find the Area Decomposing polygons to find the area is something that you can do with a shape like a trapezoid. Decompose polygons to find the area with help from an experienced mathematics educator in this free video clip. Transcript How to decompose polygons to find the area. I'm Bon Crowder and we're talking about taking apart polygons so we can look at their areas. How to convert amps to watts (W) How to convert electric current in amps (A) to electric power in watts (W). You can calculate watts from amps and volts. You can't convert amps to watts since watts and amps units do not measure the same quantity. Hexagon Geometry Puzzle A quick little geometery puzzle this week, shown to me by a friend. It's not too challenging. If the regular hexagon above is one square unit, what is the area of the yellow quadrilateral? It looks complicated at first but, actually, we don't need to worry about angles, we can simply work with symmetry. The hexagon contains six equilateral triangles (shown in red below). Each of these triangles is 1/6 of the area of the large hexagon.

Van der Waerden numbers Van der Waerden's theorem is a theorem in the branch of mathematics called Ramsey theory. It relates to ways that collections can be coloured, in order, avoiding spacing of colours that are a defined length arithmetic progression apart. They are named after the Dutch mathematician B. How to calculate cubic feet Article Category: Units | 0 Comments It's not an everyday problem, but there will be times when you need to calculate the capacity of something. Instead of staring blankly into the trunk of your car, getting a tension headache trying to find the biggest bathtub, or weeping when confronted by the decision over buying a new fridge-freezer or oven, just take control! How to do it There are only three measurements you need to take to work out the volume or capacity in cubic feet: length, width and height.

Metric to Standard Conversion Chart (US) Welcome to the Math Salamanders' Metric to Standard Conversion Charts. Here you will find a range of different charts to help you to convert from one unit of measurement to another. Here you will find a range of Metric to Standard Conversion charts. Hare and Hounds Puzzle Hare and Hounds On each turn, a single hound moves to a directly connected empty square, followed by the hare's similar move. The hounds may only move vertically or forward (to the right), not backward. The hare may move in any direction. There are no captures. The hounds win by trapping the hare so that he is unable to move.

Names of Geometric Shapes—With Pictures Most children know the names of basic two-dimensional shapes before they enter school. Squares, triangles, circles, and ovals are easy for young children to recognize and draw, even if their other math skills are still developing. As they get older, they can discern more differences among shapes and start to learn more precise words for the wide variety of geometric objects they encounter in life. Soon, they begin to learn names of three-dimensional figures like cubes, cones, cylinders, spheres, and more.

Three-Dimensional Shapes This page examines the properties of three-dimensional or ‘solid’ shapes. A two-dimensional shape has length and width. A three-dimensional solid shape also has depth. Three-dimensional shapes, by their nature, have an inside and an outside, separated by a surface. All physical items, things you can touch, are three-dimensional. This page covers both straight-sided solids called polyhedrons, which are based on polygons, and solids with curves, such as globes, cylinders and cones. How to Find and Apply The Slope of a Line In this lesson, we'll discover all about the slopes of lines. We'll learn about different types of slopes and how to find the slopes of lines. We'll use two methods: the slope formula and the slope-intercept form. Explore our library of over 10,000 lessons Click "next lesson" whenever you finish a lesson and quiz. Got It
