WebThe Mathematics Behind It. The Pythagoras Theorem says: In a right-angled triangle, the square of a (a 2) plus the square of b (b 2) is equal to the square of c (c 2 ): a 2 + b 2 = c 2. Let's check if it does work: 3 2 + 4 2 = 5 2. Calculating this becomes: 9 + … WebA Right Triangle's Hypotenuse. The hypotenuse is the largest side in a right triangle and is always opposite the right angle. (Only right triangles have a hypotenuse ). The other two sides of the triangle, AC and CB are referred to as the 'legs'. In the triangle above, the hypotenuse is the side AB which is opposite the right angle, ∠ C .

Circle Theorems - Mathematics GCSE Revision

WebAn inscribed angle has its vertex on the circle. ∠ABC, in the diagram below, is called an inscribed angle. The angle is also said to be subtended by (i.e. opposite to) arc ADC or … WebThe theorem can also be thought of as a special case of the intersecting chords theorem for a circle, since the converse of Thales' theorem ensures that the hypotenuse of the right angled triangle is the diameter of its circumcircle.. The converse statement is true as well. Any triangle, in which the altitude equals the geometric mean of the two line segments … how do i clear my i phone memory compleatly
