• A obtuse triangle is a triangle with one angle greater than 90 degrees.
• To find the area of an equilateral triangle, use the formula A = (√3/4) * s^2
• The sum of the interior angles of any polygon can be found by multiplying the number of sides by 180 degrees, then subtracting 360 if there are more than three sides.
• An acute triangle is a triangle where all angles are less than 90 degrees.
• A prime number is a whole number greater than one that has no positive divisors other than one and itself.
• Linear equations with coefficients represented by variables can be solved if the coefficients satisfy certain conditions.
• The solutions of a linear equation in two variables can be obtained by the method of substitution, elimination or cross-multiplication.
• Two linear equations with two variables can have zero, one or infinite number of solutions.
• A right triangle can also be an isosceles triangle if the two shorter sides are equal in length.
• The product of two numbers is the result when they are multiplied together.
• An isosceles triangle is a triangle with at least two sides of equal length.
• The perimeter of a regular polygon can be found by adding up all its sides.
• In a right-angled triangle, the side opposite the right angle is called the hypotenuse.
• If two lines intersect at right angles, they form a rectangle.
• In a right-angled triangle, the side opposite the right angle is called the hypotenuse.
• The circumference of a circle is calculated using the formula C = 2πr or C = πd
• If the graphs of two linear equations intersect at only one point, they represent the same line and their solution set consists of this single point.
• If the graphs of two linear equations intersect at only one point, they represent the same line and their solution set consists of this single point.
• In the quadratic function f(x) = ax^2 + bx + c, the vertex form is used to determine the minimum or maximum value of the function.
• In the quadratic function f(x) = ax^2 + bx + c, the vertex form is used to determine the minimum or maximum value of the function.
• If two lines intersect at a point, they form four angles - two pairs of adjacent angles.
• If two lines intersect at a point, they form four angles - two pairs of adjacent angles.
• A reflex angle is an angle greater than 180 degrees but less than or equal to 360 degrees.
• The quotient of two numbers is the result when the first number divides into the second number.
