In the picture on the right, you can see a dihedral angleon the inside of a cube. The difference is the answer you get when you subtract one number from another number.įor more info, check out my Subtraction Lessons.ĭigits are the numbers we use for counting: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9Ī dihedral angle is the interior angle formed by two planes - usually in three dimensional geometric figures like polyhedra. The diameter also cuts across the thickest part of the circle. The diameter is a chord (a line segment) that passes through the center of the circle. The denominator is the bottom number in a fraction.įor more info, check out my lessons on fractions. The purple polynomial below has a degree of 10 since 8 + 2 = 10 and that's the biggest one.įor more info, check out my algebra lesson on polynomials. The green polynomial below is a 3rd degree polynomial because the biggest power is a cube. To find the degree of a polynomial, just find and count the biggest exponents. One-fourth of a pizza would be 0.25 of a pizza.įor more info on decimals, check out my decimal lessons.Ī degree is a special unit of measure that measures things that are circular - like angles that sweep around! To show that a measurement is a degree, you use a little circle after the number. You can use a decimal number to count part of the pizza. ) count whole things - like a whole pizza. Decelerating is slowing down.ĭecimal numbers are like fractions because they count PART of something. It just means that the speed is changing. In physics, you just say ' acceleration' whether you are speeding up or slowing down.

Decelerationĭeceleration is a slowing down of your speed (velocity). measurement, a decameter is about 32.808 feet. The picture on the right is a regular decagon since all the sides and angles are the same ( congruent.)įor more info, check out Properties of Decagons.Ī decameter is 10 meters (in the metric system). Just scroll down or click on the word you want and I'll scroll down for you!Ī decagon is a ten sided polygon. Easy to understand math definitions for K-Algebra mathematics
