There are ___ vertex in a triangle

Find the locus of the vertex of a triangle with fixed base and having constant area

Find the locus of the vertex of a triangle whose, sum of base angles is fixed.

In an isosceles triangle,if the vertex angle is twice the sum of the base angles,then the measure of vertex angle of the triangle is 100^(0) (b) 120^(0) (c) 110^(0) (d) 130^(0)

If one of the equal angles of an isosceles triangle is65^(@), then the angle at the vertex is triangle is,

Two vertices of a triangle are (4,-5) and (-5,-2). If the centroid of the triangle of the origin determine the third vertex of the triangle.

The line segment from the vertex of a triangle perpendicular to its opposite side is called _____

The centroid of a triangle is (2,3) and two of its vertices are (5,6) and (-1,4) .The third vertex of the triangle is

If the altitude from one vertex of a triangle bisects the opposite side; then the triangle is isosceless.
