![]() Compute the area of quadrilateral (trapezium) ABCD?Ĭompute the area of the quadrilateral ABCD in the figure. In the figure ABCD, AB parallel to CD and the distance between them is 8 cm. Study with Quizlet and memorize flashcards containing terms like In parallelogram ABCD, what is DC, In parallelogram LONM, what is OM, What is the measure of angle. If produced PQ meets at BC at R then prove that R is the. If produced PQ meets at BC at R then prove that R is the midpoint. ABCD is a parallelogram in which P is the midpoint of DC and Q is point on AC such that CQ 1 / 4 AC. Draw an arc of radius 4 cm with centre B as centre and radius 4 cm and draw another arc with D as centre and radius 6 cm. ABCD is a parallelogram in which P is the midpoint of DC and Q is point on AC such that CQ1/4 AC. First, it is clear that the opposite angles must be equal ( angle A angle C. Several important properties then follow. In the diagram of a general parallelogram above, AB DC ABDC and AD BC ADBC. In the circle (as shown in the picture) mark a point D and join AD. The fundamental definition of a parallelogram is as follows: A parallelogram is a quadrilateral whose opposite sides are parallel. Draw a circle with centre A and radius 4 cm \(\frac\)ĭraw a parallelogram of sides 6 cm, 4 cm and area 18 cm 2.ĭraw a line AB of length 6 cm. Show that the line segments AF and EC trisect the diagonal BD. The diagonals of the rhombus intersect at O and they bisect each other at right angles. Ex 8.2, 5 In a parallelogram ABCD, E and F are the mid-points of sides AB and CD respectively. Ii.The area of the small rhombus is 3 square centimetres. Prove that this quadrilateral is a rhombus. In the figure, the midpoints of the diagonals of a rhombus are joined to form a small quadrilateral: Then the area of parallelogram ABCD is c m 2. What is the area of the ground bounded by the rope? In the given figure, ABCD is a parallelogram in which AB CD 5 cm and BD DC such that BD 6.8 cm. What is the distance between the other two corners? The distance between a pair of opposite corners is 16 metres. What is the area of the parallelogram?Īrea of parallelogram = one side × distance to the opposite sideĪ 68 centimetre long rope is used to make a rhombus on the ground. The area of the dark triangle in the figure is 5 square centimetres.
