tangent to a circle construction 8.avi

Radii To Tangents - Concept Explanation When a radius is drawn to a point of tangency, the angle formed is always a right (90 degree) angle. This fact is commonly applied in problems with two tangent segments drawn to a circle from a point. If two radii to tangents are drawn in, a kite with two right angles is formed and the missing angles or sides can be found. Related topics include central angles, tangent segments to a circle, and chords. Transcript When we have a tangent to a circle which means it's a line or line segment or even a ray that intersects the circle on only one point if we had to draw a radius to that point, something special happens. Over here I've written a tangent to a circle is and I left it blank purposely perpendicular to the radius drawn at the point of tangency so I can label this as a 90 degree angle. You're going to apply this in lots of different problems where you see a tangent in some form being d... more

Victor Vasarely Part 1

Hungarian-born Victor Vasarely is known as a founder of optical art. Vasarely was born in Pecs and grew up in Piešťany (then Pöstyén) and Budapest where in 1925 he took up medical studies at Budapest University. In 1927 he abandoned medicine to learn traditional academic painting at the private Podolini-Volkmann Academy He studied at the Bauhaus Muhely in Budapest and in 1930 emigrated to Paris where he developed his particular vision which stems from the idea of democratizing the art object. Influenced greatly by the problems of the world's cities, he feels his work offers a solution by presenting a clear view of the "color-surface-perception" relationship. Vasarely eventually went on to produce art and sculpture mainly focused around the area of optical illusion. Over the next three decades, Vasarely developed his style of geometric abstract art, working in various materials but using a minimal number of forms and colours.

Bridget Riley. Op art

Bridget Louise Riley, pintora inglesa, figura destacada dentro del movimiento artístico del Op Art. Creó complejas configuraciones de formas abstractas diseñadas para producir efectos ópticos llamativos. Riley nació el 25 de abril de 1931 en Norwood; allí estudió entre los años 1949 a 1952 en el colegio normal superior de Norwood, donde se especializó en dibujo, y más tarde en la Royal Academy. A finales de la década de 1950 le influyó el puntillismo de Georges Seurat, ya que el pintor Maurice de Sausmarez, gran admirador de la obra de Riley, a la que más tarde dedicaría un trabajo monográfico (1970), la persuadió para estudiarlo. Sin embargo, Riley alcanzó una gran reputación a través de las obras abstractas que ejecutó en la década de 1960, celebrándose más tarde diferentes exposiciones retrospectivas de sus trabajos, como la que organizó en 1971 la Galería Hayward.
