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..

If two adjacent angles are supplementary, their exterior arms lie in a straight line. If two lines intersect, the vertically opposite angles so formed are equal. When a number of lines meet at a point, the sum of the angles so formed is 360 ..

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 and (ii) ..
