The sum of the lengths of sides of a triangle is known as its (a) area           (b) height          (c) perimeter  (d) region

If the perimeter of a triangle is 6, then its maximum area is

Line segments joining the vertices to the mid-points of the opposite sides to a triangle are known as (a) medians (b) altitudes (c) heights (d) angle bisectors

A perpendicular drawn from a vertex to the opposite side of a triangle is known as (a) an altitude (b) a median (c) an angle bisector (d) a bisector

If the sum of the lengths of the hypotenuse and another side of a right-angled triangle is given, show that the area of the triangle is maximum when the angle between these sides is pi/3dot

If the sum of the lengths of the hypotenuse and another side of a right-angled triangle is given, show that the area of the triangle is maximum when the angle between these sides is pi/3dot
