Question

Show that the diagonal of a triangle divides it into two triangles equal area

​

Answer 1

Step-by-step explanation:

Show that the diagonal of a triangle divides it into two triangles equal areaGiven: A parallelogram ABCD.

Given: A parallelogram ABCD.

To prove: ar (ABC) = ar (CDA)

In ABC and ADC,

AB = CD                                             (opposite sides of a parallelogram)

BC = DA                                             (opposite sides of a parallelogram)

AC = CA                                             (common)

ABC CDA                             (SSS)

Hence, ar (ABC) = ar (CDA)               (congruent figures have equal areas)

Answer 2

Answer:

here ABC is a triangle .

AD is its diagonal and it is dividing it into two parts
