Question 1 - Question: ABC is a triangle in which AB=AC. D is a point on BC produced. Prove that AD>AB. Answer: Given: AB=AC D is a point on BC produced. To prove: AD>AB Proof AB=AC (give..

Theorem 2 - The opposite sides and angles of a parallelogram are equal. ABCD is a parallelogram. (i) AB = CD AD = BC (ii) Join A..

Theorem 4 - If a pair of opposite sides of a quadrilateral is equal and parallel, it is a parallelogram. ABCD is a quadrilateral. AB || DC and AB = DC. ABCD is a parallelogram. BC || AD Join AC and name the angles as shown We may use numbers or alphabets while referring to angles to make the proof ..

Geometrical figures help us to understand various geometrical concepts. When we prove geometrical propositions by logical reasoning, we draw only a rough figure and we do not need to take accurate measurements but geometrical constructions have to be drawn accurately to the give..

Statistics is about collection of information and its presentation and about drawing inferences from these. We come across facts and figures in the newspapers, Television and the radio. The numerical figures are called "the data". If we have to draw good inferences from informat..

A triangle is a geometrical figure formed by three lines, which intersect each other and which are not all concurren..

We are familiar with plane figures bounded by straight line segments as sides. They are known as Polygons . Polygon is a word of Greek origin. It means figure with many angles implying many sides. Squares, rectangles and other four-sided geometric figures formed by the..
