We have a trapezium (a quadrilateral with one pair of parallel sides) ABCD, where AB and CD are the (parallel) bases. The perpendicular bisector of side AD intersects with side BC at point E. A line parallel to the line AE and passing throught the point C intersects with side AD at point F...
Hi so I'm stuck on another geometry problem:
ABCD is a trapezium with a semicircle, centre O, inscribed in it.*
If AO=OD, prove that (AO)(OD)=(AB)(CD).
I've tried Pythagoras' theorem on the radius, and extending AB and CD to meet but neither of them work. I'd appreciate any hints. Thanks...
With a small semicircle at the top and three semicircles equal in area around.
Two horizontals and two diagonals.
Diagonals 1m 1m
Horizontals 1m 1dm
Just thought this would be cool, it might have some use, I don't know.
If the trapezium rule is used to measure the integral of f(x)dx between 1 and 0 on the x axis, by splitting the interval 0<= x <= 1, into 10 intervals then an overestimate of the integral is produced. So why does the trapezium rule of 10 intervals underestimate the integral (between 1 and 0)...

The whole exercise is as follows: What's the lateral surface area of this
I somehow managed to find out that the base is a trapezium, which looks like that:
And now my job is to find x. I'd be glad...
1.Find the area of an isosceles trapezium if its height is h, if the prong is seen from an angle of 60 degrees from the center of the described circle.
I am out of ideas. Don't know how to use the 60 degrees.
2.The bases of a trapezium are 25cm and 15cm, and one prong is 8cm. Calculate the...
On the picture below, I got a isosceles trapezium whose diagonal divides the bigger angle on two equal angles. b=1cm, S=13cm.
I Have to calculate the area of this trapezium, but what bothers me is: How to prove that a=c? Any help appreciated...
PQRS is an isosceles trapezium, where PQ is parallel to SR and PS=QR. PS and QR are extended to meet at O. Prove that SO=RO.
Please check the image below for the diagram.
Hey guys i need help on this aspect of maths, see im revising for an exam and need to know the method of working out for these types of questions so i can do it successfully in my exam. Please help me !!!!
(a) Determine whether the following series are convergent or divergent, justifying...
