Let’s discover some more circle theorems so that we can solve all types of geometrical puzzles. We discovered these 4 theorems in part 1: Angle at the centre is double the angle at the circumference The angle in a semi-circle is 90 degrees Angles in the same segment are equal / Angles subtended by
On a circle, the tangent is always perpendicular to the radius. We use this key piece of information when finding the equation of the tangent. We then use our knowledge of the equation of a circle, and the equation of straight lines (y = mx + c) to find the equation of the tangent. Equation Of A Ci

Thousands of years ago it was discovered that the two smaller squares on the side of a right angle triangle added up to the exact same size as the larger square on the triangle - the square formed on the diagonal side. This is called Pythagoras Theorem. VISIT us at www.fuseschool.org, where all of

Social intelligence is the ability to know oneself and others in order to be able to correctly assess one's own actions and those of other people. It is made up of five skills: sympathy, self-awareness, empathy, metacognition and theory of mind. Those who lack social intelligence can misunderstand o

Triangles are the building blocks of all other straight-edged shapes. They were used for hundreds of years to create accurate maps and GPS today still works using trigonometry. Even the pixels on phones and screens use trigonometry.We need to know these things so that we can work out exact length
