Corresponding Angles: Theorem & Examples

Angle is formed by two rays that have a common end point. There are some types of angle. Here they are. Type of Angle In general, there are some kinds of angles: 1. Acute angle (less than 90°) Learn more about acute angle. 2. Right angle (90°) 3. Obtuse angle (more than 90° but less than

Counting Numbers

Counting numbers are the set of numbers that we use to learn how to count. They are also called natural numbers, since they feel natural to us because they are naturally the first numbers to learn. Sometimes they are also referred to as positive integers. Counting: Number Names to 100 1 2 3 4 5

Reflex Angle

A Reflex Angle is more than 180° but less than 360° More Examples of Reflex Angle Which Angle? Remember to look carefully at which angle you are being asked to name. The reflex angle is the larger angle. It is more than 180° but less than 360° If you choose the smaller angle you might

Inequalities: Definition, How to Solve, Linear, Quadratic, Examples

Definition of Inequalities Inequalities is different with equality clearly. Equality use equal sign (=) but inequality use inequal sign (≠, >, <, ≤, ≥). Look at the table to understand about the inequality signs. Sign Meaning Example ≠ Not equals with … 1 ≠ 2 ≥ Greater than or equal to … a2+1 ≥ 10for

Concentric Circles

In geometry, 2 or more objects are said to be concentric, coaxial, or coaxal when they share the same axis or center. Circles, regular polygons, regular polyhedra, spheres, and cylinders may be concentric to one another (sharing the same center point). Definition of Concentric Circles Concentric Circles are 2 or more circles which have same center point. They fit inside each

Sets Theory

A set is a collection of distinct objects, considered as an object in its own right. For example, the numbers 1, 3, and 5 are distinct objects when considered separately, but when they are considered collectively they form a single set of size three, written {1, 3, 5}. The concept of a set is one


Definition Fraction is a number written with a numerator and a denominator, in which both are natural numbers. Numerator: the top number of fraction Denominator: the top bottom of fraction So, fraction is written as Numerator / Denominator Examples Fraction Numerator Denominator 1 2 2 3 3 4 7 40 99 123 Learn More Simplest

Simplest Form of Fractions

Simplest form of A fraction is a fraction that has the top and bottom cannot be any smaller (simplified), while still being whole numbers. How to simplify a fraction? Divide the top and bottom by the greatest number that will divide both numbers exactly (Greatest Common Factor), they must stay whole numbers. Examples Fraction Greatest

Metric Mass (Weight)

Mass: how much matter is in an object. We measure mass by weighing, but Weight and Mass are not really the same thing. The most common measurements: Grams Kilograms Tonnes Grams Grams are written as g (for short), so 250 g = 250 grams Kilograms 1 kilogram = 1,000 grams Kilograms are written as kg
