In this picture,the mid pointsof the sides of the large triangle are joined to make a small triangle inside. Calculate the coordinates of the vertices of the large triangle.

Consider a triangle whose sides are y = x, y = 2x and y = 3x + 4 Find the co-ordinates of the vertices of the triangle.

Calculate the perimeter of the triangle shown below. .

Calculate the perimeter and area of the triangle in the picture.

In the figure small triangles are drawn joining the mid points of large triangle. Find the length of sides of large triangle.

In the picture, the perpendicular is drawn from the midpoint of the hypotenuse of a right triangle. to the base. Calculate the length of the third side of the large right triangle and the lengths of all three sides of the small right triangle.

Calculate.the perimeter and area of the triangle in the picture.

In the picture below, the top vertex of a triangle is joined to the midpoint of the bottom side of the triangle and then the midpoint of this line is joined to the other two vertices. Prove that the areas of all four triangles obtained thus are equal to a fourth of the area of the whole triangle.
