Pre-Algebra; Introducing Algebra. Overview; Operations in the correct order; Evaluate expressions; Identify properties; Equations with variables; Coordinate system and ordered pairs; Inequalities
A triangle has three angles. The sum of the measures of the angles is always 180° in a triangle. We have different types of triangles. A triangle is classified by its angles and by the number of congruent sides. A triangle that has three acute angels is called an acute triangle.
Adding and subtracting integers. Do excercises Show all 3 exercises. Addition and subtraction I. Addition and subtraction II. Addition and subtraction III. You already know how to add 3 + 4 and so on. But there are many ways to add integers. One way to add integers is by using a number line. Example.
Geometry is the fourth math course in high school and will guide you through among other things points, lines, planes, angles, parallel lines, triangles, similarity, trigonometry, quadrilaterals, transformations, circles and area.
Angles and parallel lines. Do excercises Show all 3 exercises. Opposite angles I. Opposite angles II. Opposite angles III. When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles.
Algebra 1; How to solve linear equations. Overview; Properties of equalities; Fundamentals in solving equations in one or more steps; Ratios and proportions and how to solve them; Similar figures; Calculating with percentages
Expressions and variables III. An algebraic expression comprises both numbers and variables together with at least one arithmetic operation. Example. 4 ⋅ x − 3 4 ⋅ x − 3. A variable, as we learned in pre-algebra, is a letter that represents unspecified numbers.
