Draw a triangle ABC where vertices A, B and C are (0, 2), (2, -2), and (-2, 2) respectively.
Plot the point A by taking its abscissa 0 and ordinate as 2.
Similarly, plot points B and C. Join A, B and C. This is the required triangle.
Draw the graphs of: [4 MARKS]
(a) 3x-2y = 6 and y = -2 on the same pair of axes. (b) A triangle ABC where vertices A, B and C are (0, 2), (2, -2), and (-2, 2) respectively.
Prove that in any △ABC, cos A=b2+c2−a22bc, where a, b and c are the magnitudes of the sides opposite to the vertices A, B and C, respectively.
If an equilateral triangle ABC is drawn as shown below with A(0,0) and a side of 4 units then the other two vertices of the triangle are___
