Speed Speed is how fast something is moving, how far it travels in a given time.speed = distance ÷ time Examples: 1) I travelled 270 km and the trip took 3 hours. Average speed. speed = 270 : 3 = 90 km/h 2) The speed of the car is 90 km/h. It takes 4 […]

Regular Polygon
Regular polygon Regular polygons have all sides equal and all angles equal. Angle formulas for regular polygons n – the number of sides Area and perimeter of regular Polygons Area = (n × a × apothem) / 2 r – apothem is the radius of the inner circle […]
Units of speed
Units of speed Speed is a measure of how fast something is travelling. Speed is distance divided by time. The most common units of speed are metres per second (m/s), kilometres per hour (km/h) andmiles per hour (mph). The formula for speed is speed = distance ÷ time.To work out what the units are for speed, you […]
Coordinate plane
Coordinate plane A coordinate plane (Cartesian plane) is a plane formed by a horizontal line (an axis) and a vertical line (another axis) that intersect at a point called the origin. A plane containing two perpendicular axis (x and y) intersecting at a point called the origin (0,0).A point position is denoted using pairs of coordinates (x; y) , e.g. A(3, 1). The […]
Height
Height The height is the measurement of the distance of an object from the base to the top. In geometry it is called altitude. The term height in geometry refers to the measurement of an object along the y-axis in coordinate geometry. Example of height in math is shown bellow. […]
Multiplication
Multiplication Multiplication is the process of calculating the product of two or more numbers. The multiplication of numbers say, ‘a’ and ‘b’, is stated as ‘a’ multiplied by ‘b’. In Maths, the basic explanation of multiplication is adding a number, with respect to another number, repeatedly. Multiplication is the process of calculating the product of two […]

Triangle
Triangle A triangle is a plane figure with three straight sides and three angles. The angle formed inside the triangle is equal to 180 degrees. It means that the sum of the interior angles of a triangle is equal to 180°. A triangle is a plane figure with three straight sides and three angles. The […]
