For the Annual Sports Day, the school plans to decorate the boundary of the ground using wooden frames of different quadrilateral shapes:
Frame \(X\) is in the shape of a trapezium, Frame \(Y\) is a rhombus used at the centre and Frame \(Z\) is a kite used near the entrance.
Based on the given information solve the following questions
1. While installing Frame \(X\), the techinician observes that the two angles on one slant side always form a straight angle. Which concept explains this?
2. If one interior angle of the frame B is \(70^\circ\)
, what will be the measure of its adjacent angle?
3. While assembling Frame \(Z\), it is observed that one diagonal divides the frame into two congruent triangles. Which property explains this?
4. If one diagonal of frame\(Y\) is slightly increased while keeping all sides equal, which of the following will definitely change?
