In figure AngleQPR > AnglePQR
Let's write the relation between PR and QR
Q
R
2. In triangleABC, AC >AB. D is any point on the side AC such that AngleADB = AngleABD. Let's
prove that AngleABC > AngleACB.
3. In triangle ABC, AB > AC; then the bisector of AngleBAC intersects BC at D. Let's prove
that BD< CD
4. In triangleABC, AD is perpendicular to BC and AC > AB. prove that
(i) AngleCAD> Angle BAD (ii) DC >BDI
5. In a quadrilateral the greatest and the smallest sides are opposite to each other.
Let's prove that the adjacent angle to the greatest side is smaller than its opposite side.
