Question

A triangle has vertices at points (0,0). (a, b), and (2a, 0). Select all points that lie on the sides of the triangle.

A. (a,0)
B. (0,5)
C. (-a,b)
D. (a/2, b/2)
E. (a/3, b/4)

Answer 1

A. (a,0)

D. (a/2, b/2)

Explanation:

Let's assume a and b means x and y coordinate if the x and y axes.

So the coordinates are now (0,0) ,(x,y) , (2x,0)

So all point from 0 to 2x lies on the sides of triangle

And all points from 0 to y lies on the

sides of the trianglee.

So we have three. Equation of the triangle .

One is x= y

So (a/2, b/2) is correct.

Second is 2x = 0y

So (a,0) is correct.
