opposite angles of rhombus

Angle of Friction - 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 ..

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..

Choose the quadrilaterals whose diagonals intersect at right angles. 1. Square 2. Rectangle 3. Kite 4. Rhombus => 1, 3 and 4 or 1 and 3 or 1, 2 and 3 or 1, 2, 3 and 4..

A triangle PQR has sides of lengths 27 units, 36 units and 45 units. What is the measure of the angle opposite to the longest side? => 60 or 90 or 45 or 180..

If the length of the hypotenuse of a 30° - 60° - 90° triangle is 28 cm, then the length of the leg opposite to 30° angle is => 10 3 cm. or 1 cm. or 14 cm. or 20 2 cm...

Which quadrilateral has two pairs of congruent adjacent sides and no opposite sides congruent? => rhombus or kite or parallelogram or trapezoid..

A tree stands vertically on the bank of a river. The angle of elevation of the top of the tree from a point on the other bank directly opposite to the tree is measured as 70°. The angle of elevation of the top of the tree from 15 ft behind this point on the same ba..

If A(0,0) , B(5, 0) , C(8, 4) and D(3, 4) are the vertices of a rhombus, then angle between the diagonals of it is _________. => a reflex angle or an acute angle or an obtuse angle or a right angle..

Two adjacent angles are said to form a linear pair of angles, if their non-common arms are two opposite rays. Recall adjacent angles. Now observe the pairs of angles in the figure. ..

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..
