The triangle shown below isequilateral:Find the coordinatesof its vertices.

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.

Suppose that two opposite vertices of a square are (1,2) and (5,8) Find the co-ordinates of its other two vertices

The coordinates of the vertices of a triangle are(-1,5),(3,7),(1,1).Find the coordinates of its centroid.

Suppose that A (2,6,-4), B(4,-2,3) and C (x,y,z) are the vertices of a DeltaABC Find the co-ordinates of the centroid of the triangle.

Prove that the two triangles shown below have the same area

The vertices of a family of triangles have integer coordinates. If two of the vertices of all the triangles are (0,0) and (6,8) then the least value of areas of the triangles is

Draw the triangle shown below in your note book. Draw triangle ABP, BCQ, CAR of same area with measurements given below. angleBCQ = 60^@
