Hi can you please help me with this
thank you
The area of a triangle is 4 times the area of the smaller triangle formed by joining the midpoints of two sides True or false. Draw a counterexample to show if it's false.

joining the midpoints means that the smaller triangle is half the height
... and half the base length of the larger triangle
use the triangle area formula to find the relationship
k * [1/2 * (b/2) * (h/2)] = 1/2 * b * h ... solve for k
... and half the base length of the larger triangle
use the triangle area formula to find the relationship
k * [1/2 * (b/2) * (h/2)] = 1/2 * b * h ... solve for k
