Basic Proportionality Theorem - A line parallel to one side of a triangle divides the other two sides into parts of equal proportion. In triangle ABC, a line drawn parallel to BC cuts AB and AC at P and Q respectively. Let the point P divide AB in the ratio of l: m where l and m are natur..

Basic Terms Connected to Waves - The four important terms used in the study of waves are Wavelength, Amplitude, Frequency and Wave velocity. Wavelength ' l ' is the distance between two consecutive points on the wave which are in the same phase. (same phase means same state of vibrations)..

Basic Proportionality Theorem (B.P.T.) will be more useful in the topic 'SIMILARITY'. Division of a line segment into equal parts. Divide a line segment of length 8.4 cm into 5 equal parts. AB = 8.4 cm 1. Draw AB = 8.4 cm and through A draw another line AX at an acute angle to AB. 2. With..

You may have observed that, when coal, coke or charcoal is burning, a pale blue flame is visible (Fig.11.1). The blue flame is actually due to the burning of carbon monoxide. When the supply of oxygen is in plenty, carbon initially burns to form carbon dioxide. In the midst of the fire,..
