What is the temporary assumption used to prove that   “If a + b ≠ 18, and a = 16 then b ≠ 2”?

 

In the given figure AB = CD,

If ∠CAB > ∠DCA then,

In the given figure AB = CD,

If AD > BC then,

Indirect proof is also called ____

If G is the centroid of triangle ABC,

Find GD.

Centroid divides a median in the ratio 2:1

If G is the centroid of triangle ABC,

Find BG.

BE= 12

If G is the centroid of triangle ABC,

Find BE.

BG = 4x + 4
BG = 2/3 BE
4x + 4 = 2/3 (7x + 5)
12x + 12 = 14x + 10
2x = 2
x = 1
BE = 7x + 5
= 12

If G is the centroid of triangle ABC,

Find CG

>>>CG was given as 5x+1 and CF can be found in terms of x.
>>>There is no scope to find the value of x.
>>>Hence, we have no way to find the value of CG.

If G is the centroid of triangle ABC,

Find AG

Centroid divides a median in the ratio 2:1

If G is the centroid of triangle ABC,

Find x.
