opposite angles of rhombus

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..

To determine the angle of minimum deviation the side AB of the prism is made to face the ray of light. On looking through the face AC and rotating the prism table, the image of slit also turns. For a particular position of the prism, the slit becomes stationary. On further rotating the p..

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..

Tom and Sam are on the opposite sides of a tower of 160 meters height. They measure the angle of elevation of the top of the tower as 40° and 55° respectively. Find the distance between Tom and Sam. => 308 m or 313 m or 303 m or 306 m..
