WebML Aggarwal Solutions for Class 9 Maths Chapter 11 – Mid Point Theorem. Exercise 11 1. (a) In the figure (1) given below, D, E and F are mid-points of the sides BC, CA and AB respectively of Δ ABC. If AB = 6 cm, BC = 4.8 cm and CA = 5.6 cm, find the perimeter of (i) the trapezium FBCE (ii) the triangle DEF. (b) In the figure (2) given below, D and E are mid … 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°. dancing with the stars sadie robertson mario
