geometry rectangle construction

Diagonal and the angle included by them are given. A Rectangle ABCD, given AC = 7cm, BC = 7 cm and the angle included by them is 60 o . (i) Draw AC = 7 cm. (ii) Construct its perpendicular bisector to obtain the midpoint O. (iii) At O, construct COX = 60 o ..

Summary - In a polygon of 'n' sides, the sum of the interior angles is equal to (2n - 4) right angles. Each interior angle of a regular polygon is If the sides of a convex polygon are produced, in order, the sum of the exterior angles is 4 right angles. Each exterior angle of a regular polygon of n..

Question: Show that the quadrilateral formed by joining the mid-points of the sides of a square is also a square. Answer: Given: ABCD is a square. P, Q, R and S are mid-points of AB, BC, CD and DA respectively. To prove: PQRS is also a square. Construction: Join the di..
