opposite angles

A pair of angles are said to be alternate angles if (i) both are interior angles (ii) they are on the opposite sides of the transversal and (iii) they are not adjacent angles. Alternate angles are some times also called alternate interi..

A Corollary is an easy consequence of a theorem. It two lines intersect, then the vertically opposite angles so formed are equal, and When a number of lines meet at a point, the sum of the angles so formed is four right angles..

Consider a block placed on a rough floor. Now, the reaction force is because it is equal and opposite to the weight . Now apply a horizontal force so that the block just begins to slide, i.e., the frictional force is equal to the limiting friction. When this condition is satisfie..

In triangle ABC, if a = 7, b = 9, and c = 11, then find the measure of the angle to the nearest degree, opposite to the longer side. => 76° or 115° or 55° or 86°..

Anny is at an Ice-cream parlor where, the path RP to her house and the path RQ to her school meet at right angle. She goes into the shopping complex, which is exactly opposite to the Ice-cream parlor. Find the distance between her house and the shopping complex. [Given a = 174 a..

Interior and Exterior angles of a triangle - In a triangle when we refer to an angle, we mean the angle bounded by the two sides. The three angles lie in the interior region of the triangle. These angles are called the interior angles of t..

In a triangle when we refer to an angle, we mean the angle bounded by the two sides. The three angles lie in the interior region of the triangle. These angles are called the interior angles of the triangle. Now observe the triangle in which the si..

From the top of a building of height h meters in a street, the angles of elevation and depression of the top and the foot of another building on the opposite side of the street are θ ° and φ ° respectively. Find the height of the opposite building. [G..

To solve a right angled triangle, we need to find out the unknown sides and the angles with the help of t-ratios. To find a side, usually we take such t-ratios that involve the unknown sides. We have taken A because, the side opposite to A is the un..

Solution of Right Angled Triangles - To solve a right angled triangle, we need to find out the unknown sides and the angles with the help of t-ratios. To find a side, usually we take such t-ratios that involve the unknown sides. In the figure, AB = 100 cm, find (i) x a..
