In Euclidean Geometry, a quadrilateral is defined as a polygon with four sides and four vertices.. Quadrilaterals are either simple or complex. We don't know the two sides so we are going to do something to find these missing sides. Trigonometry Ratios. This video screencast was created with Doceri on an iPad. Call the left right-angled triangle's lower left $\;x\;$, so that $\;X=2x\;,\;\;H=\sqrt3x\;$, and thus in the right right-angled triangle we have that the lower leg is $\;3x\;$, and its hypotenuse is $\;2\sqrt3 x\;$. This whole side is 7.8, annd the side lengths of the trapezoid are 9.9,2 , and 8. Trigonometric Ratios. Area of a Trapezium Practice Questions - Corbettmaths. What is a sector of a circle.
