WebExample 2: Find the fourth angle of the right trapezium if one of the given angles is 60°. Solution: As we know, in a right trapezium, there are 2 right angles and the sum of all the interior angles in a trapezium is always 360°. So, if one of the given angles is 60°, let the missing angle be x°. The fourth angle can be calculated as x° + 90° + 90° + 60° = 360°. WebO is the point of intersection of the diagonals AC and BD of a trapezium ABCD with AB DC. Through O, a line segment PQ is drawn parallel to AB meeting AD in P and ...

WebGiven a trapezoid ABCD with parallel sides AB and CD, with E the point of intersection of the diagonals AC and BD. If e is the line through E parallel to AB, then if e intersects BC in F and DA in G, the ratios BF/CF = AG/DG = AB/CD. Theorem Given a trapezoid ABCD with parallel sides AB and CD. Webfourth point and have all four points cyclic, then clearly this fourth point must lie on the circle that passes through the other three points. So, not every four non-collinear points are cyclic! This is a theorem about the cyclicity of four points: Theorem 2.1. Given four points A, B,C and D, they are cyclic iff either \ABC = \ADC or \ABC ... cancel spotify without logging in

WebMar 29, 2024 · Show that ABCD is a trapezium Given: ABCD is a quadrilateral where diagonals AC & BD intersect at O & 𝐴𝑂/𝐵𝑂=𝐶𝑂/𝐷𝑂 To prove: ABCD is a trapezium Construction: Let us draw a line EF II AB passing through point O. Proof: Given 𝐴𝑂/𝐵𝑂=𝐶𝑂/𝐷𝑂 ⇒ 𝐴𝑂/𝐶𝑂=𝐵𝑂/𝐷𝑂 Now, in ∆ 𝐴𝐷𝐵 EO II AB 𝐴𝐸/𝐷𝐸=𝐵𝑂/𝐷𝑂 ⇒ 𝐴𝐸/𝐷𝐸=𝐴𝑂/𝐶𝑂 Thus in Δ ADC, Line EO divides the triangle in … WebIn trapezium ABCD, AB DA and DC=2AB.
