Triangle

In technical analysis, a series of high and low prices for a security that, when plotted on a chart, looks vaguely like a triangle. A triangle indicates that investors do not know whether a bull market or a bear market will prevail. If the triangle breaks upward, it is a bullish sign, but if it breaks downward, it is a bearish sign. A triangle is also called a wedge. See also: Ascending sign, Descending sign.

triangle

In technical analysis, a chart pattern indicating the convergence in the movement of successive high and low prices and characterized by a formation that resembles a triangle turned on its side. A triangle indicates a period of combat between bulls and bears with the technical analyst having to determine the winner. If prices break out of the triangle on the upside, it is a bullish sign. A breakout on the downside indicates the bears are winners. The closer the breakout occurs to the point of the triangle, the less conclusive the signal to buy or sell. Also called coil, flag, pennant, wedge. See also ascending triangle, descending triangle.

The central square theory states that "the right side of the equation [z.sup.2] is composed geometrically of four congruent right-angled triangles rotated around a central square [(y - x).sup.2], which in turn when enclosed forms a new square about which other Pythagorean triples revolve".

QUIZ OF THE DAY

From the previous exercise it is seen that there are only two shapes; a small right-angled triangle within one square with side lengths (1, 1, [square root of (2)]) and an obtuse-angled triangle with side lengths (l, [square root of (2)], [square root of (5)]).

One way to imagine Pythagoras' theorem in a third dimension is to extend the right-angled triangle (with hypotenuse c and legs a and b) into a right prism of length l, the squares on the sides of the triangle becoming cuboids on the faces of the prism as shown in Figure 1, where the right-angled triangle is shown in black.

Due to the fact that I listened during maths lessons in schools, I know fine well that in any right-angled triangle, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares of the other two sides.

A 'How' approach would involve teaching the formula [c.sup.2] = [[alpha].sup.2] + [b.sup.2] for a right-angled triangle, explaining how to identify the hypotenuse and showcasing examples of typical questions which occur: finding the hypotenuse, finding one of the other sides, applying to 'real world' questions.
