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. In the circle (as shown in the picture) mark a point D and join AD. 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. The diagonals of the rhombus intersect at O and they bisect each other at right angles. 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: What is the area of the ground bounded by the rope? What is the distance between the other two corners? A machinist creates a solid steel part for a wind turbine engine. The distance between a pair of opposite corners is 16 metres. Score 2: The student gave a complete and correct response. This means we can use the SAS (Side-Angle-Side) congruency theorem to prove that triangle ADC is congruent to triangle CBA. Now, we have two sides and the included angle of triangle ADC congruent to two sides and the included angle of triangle CBA. 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. In step 2, we know that AC AC due to the reflexive property. The area of the dark triangle in the figure is 5 square centimetres.
