A trapezium encloses half circle bisecting its diagonals. Find angle of the trapezium. Let $ABCD$ be a trapezium with parallel sides $AB$ and $CD$ such that the circle $S$ with $AB$ as its diameter touches $CD$. Furth...
The triangles AFO and ACB are similar since AO = OB, AF = FC and shared angle $\alpha$, , which leads to BC = 2OF = 2r. From the right triangle BEC, we have $\sin\angle$BCE = BE/BC = $\frac12$. Thus, the angle is 30$^\circ$. ![enter image description here](

area of trapezium A trapezium has perpendicular diagonals and altitude 4. If one of the diagonals has length 5, find the area of the trapezium A 12 B 50/3 C 25/2 D 40/5 I guess the answer is C. I divided the trap...
Trapezium $AH=4$, $AC=5$ $\rightarrow$ $HC=3$. $\displaystyle \frac{AB}{AO}=\frac{DC}{OC}=\frac{AC}{HC}=\frac{5}{3}$.

Geometry question on trapezium A trapezium $ABCD$, in which $AB$ is parallel to $CD$, is inscribed in a circle with center $O$. Suppose the diagonals $AC$ and $BD$ of the trapezium intersect at $M$, and $OM=2$. How ...
![enter image description here]( It should be clear that $\triangle MAB$ and $\triangle MCD$ are equilateral. After dropping the perpendicular from O to AC at P, (as hinted by @Rigel), $\triangle OPM$ is a 30-60-90 special triangle with the lengths as shown. Let $PC = t$. Then, $DC = MC = t + \sqrt ...

Find the area of the trapezium ABCD is trapezium AB||CD. 10 & 40 are the areas of the respective parts !enter image description here How to find out the area of the trapezium?
If we denote trapezium total height $h$, then heights of corresponding triangles are $\frac{2h}{3}$ and $\frac{h}{3}$ (all linear ratios of triangles $ cdot h=3\cdot 40=120$, $\text{Area of} \space \triangle AOB=\dfrac{AB}{2} \cdot \dfrac{h}{3}=10$ $\implies$ $AB\cdot h = 6\cdot 10=60$; Now Area of trapezium

Are rectangles are trapezium Rectangle by definition given as the quadrilateral in which opposite sides are equal and each angle is equal to 90 degree Where as in case of trapezium any one pair of opposite sides is p...
In general by definition rectangles are not trapzeoids, only one pair of sides are parallel in a trapezoid. There are some definitions though which define parallelograms to be trapzeoids. It comes down to the definition given in class.

If two non parallel sides of trapezium are equal. Prove that it is cyclic If the two non parallel sides of a trapezium are equal then prove that it is cyclic. I know that if the two sides are parallel the trapezium w...
The trapezium is symmetric so the angles $\angle DAB$ and $\angle ABC$ are equal. So we have $\angle ABC + \angle CDA = \pi$, i.e. we have opposite angles in the trapezium add up to $\pi$.
