UNIT IV-GEOMETRY TRIANGLESProof of the following theorems are deletedThe ratio of the areas of two similar triangles is equal tothe ratio of the squares of their corresponding sides.In a triangle, if the square on one side is equal to sumof the squares on the other two sides, the angleopposite to the first side is a right angle.
CIRCLESNo deletion
CONSTRUCTIONSConstruction of a triangle similar to a given triangle
CIRCLESThere is one and only one circle passing through three givennon-collinear points.If a line segment joining two points subtends equal angle at twoother points lying on the same side of the line containing thesegment, the four points lie on a circle.
CONSTRUCTIONSConstruction of a triangle of given perimeter and base angles
