Study Notes
Circle Properties
- The formula for finding the circumference of a circle is not specified, but it is typically C = 2πr or C = πd, where C is the circumference, r is the radius, and d is the diameter.
- The diameter of a circle is equal to twice the radius (d = 2r).
- The area of a circle with radius 'r' is A = πr^2.
Triangle Properties
- In a right-angled triangle, the side opposite the right angle is called the hypotenuse.
- The sum of the interior angles of a triangle is 180 degrees.
- The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides in a right-angled triangle (a^2 + b^2 = c^2, where a and b are the other two sides, and c is the hypotenuse).
